Rate this book
A provocative, trauma-informed guide to post-monogamy—how to build liberated relationships rooted in empowerment, equity, and authenticity

With practical somatic exercises, reflection prompts and a relational toolkit—also includes a glossary of polyamory, non-monogamy, and alternative relationship terms


This book is for polyamorists who want to practice their non-monogamy with more feminism, more queerness, and more community building. It’s for monogamists who don’t want to do relationships on autopilot. It’s for everyone who dearly believes a better way to love and live exists. It’s for change makers who aspire to re-wild the ways we love.

An empowering guide to imagining (and living) better relationships, Radical Relating pushes back on the monogamy mandate. Author, somatic educator, and relationship coach Mel Cassidy explodes the often-unquestioned mainstream myths about the nuclear family those that tell us your soulmate must be your sole mate. That sex is the only yardstick of relational success. That self-sacrifice and self-denial are necessary trade-offs for security and partnership. That we need to ride the relationship escalator all the way up, or we’ll die alone.

In four sections, Cassidy explains the why, what, how, and where of the Radical Relating model.

Lay out clear-eyed analysis about why monogamy isn’t working and explain the harms of unquestioned internalized mono-normativity Offer Reflective Journaling prompts, Somatic Pauses, and practical wisdom for assembling your Relational Toolkit Explain the trauma-informed pillars of Radical Relating: Orientation, Resilience, Resolution, and Engagement Help you reorient to a new map for relating that’s queer, anarchist, and somatically integrated Help you build skills to understand and navigate your relationship landscape Explore the intersections of monogamy, colonialism, patriarchy, and capitalism and illuminate how monogamous relationship structures emerged with one goal in to consolidate capital Most books on non-monogamy focus on top-level logistics and play into beliefs that can inadvertently replicate oppressive structures. Radical Relating is it speaks to readers who want not only to open up their relationships or expand their sexual experiences, but claim a new and liberating ways to relate to each other, fulfill our authentic needs, and build true communities of care beyond monogamy.

You can tell a lot of planning and thought went into this book. It's the most accessible and extensive book on polyamory I've read, drawing from trauma-sensitive somatic and polyvagal therapy, couples counselling, nonviolent communication, anarchoqueer and feminist principles of free love coupled with accountability. As someone who's gone through the fires of trauma, dissociation, and emotional dysregulation unto reactive paranoia, avoidance, suicidality, and explosive rage, these are the kinds of book that begin the journey to healing, leading readers to alternative paths more conducive to living. Tracing anger to terror to vulnerability, disrupting the shame/blame cycle associated with vulnerability and a blocked expression of needs, rebuilding trust in oneself and the other so that such needs can be communicated, and collaboratively working together to reach an outcome driven by empathy and shared goals rather than insecurity and ultimatums.

Embodied safety is a recurring motif throughout the book. A feeling of security and connection to one's body in relation to self-knowledge, validation, communication, and consent. I really appreciated this angle, because it connected insights from attachment to somatics to mindfulness. Anxiety isn't simply racing thoughts, but the calamity of a nervous system thrown into fight, flight, freeze, or fawn. Jealousy isn't merely driven by a cognitive distortion from the past, but a breakdown in communication that results in narcissistic self-withdrawal or borderline rage and blame. We learn our triggers by learning our bodies. A form of somatic comprehension, from the way we hold our bodies (still, fidgety, withdrawn, relaxed), to the way our emotions appear as heat, constriction/expansion, pain, colour, rhythmic movements at various bodily sites. To pause is to stall reactivity so that we may trace the reactions of an action pathway conditioned by trauma. It's a Buddhist sensibility reframed through emotion psychology that works to deepen desire, rather than rid us of it.

There's also a lot of practical info on polyamory, from setting relationship boundaries to resolving conflicts with one's partners and metamours. These sections draw heavily on nonviolent communication, which orients around needs. Mel draws out the parallels between nonviolent communication and anarchy. They argue that monogamy is founded on control of one's partner based in expectations grounded in white supremacy. The need to appear successful in a cisheternormative world (married, with children, in a career pathway, towards property ownership) obfuscates genuine communication and collaboration, due to the fear of social ostracisation. While there's nothing wrong with jealousy (it's a healthy indicator of how much you value your partner), white supremacist notions of fidelity manifest possessive jealousy—that gender gatekeeping bullshit whereby any relation your partner has with the opposite sex is seen as suspicious or traitorous. Implicit or explicit rules develop under such conditions, which are used to control people's behaviours. Genuine needs aren't expressed, distressing emotions aren't processed, reactive actions take hold (passive aggressive behaviour, guilt-tripping, accusations, brooding, dismissiveness), and relationships don't develop beyond surface signs of success.

Mel's argument about white supremacy and monogamy is convincing, but as the book progressed I felt frustrated with their constant references to it. Anything connected to enforced monogamy, perfectionism (appearing successful), possessive jealousy, middleclass propriety (avoidance of conflict), and so on, were explained as a result of white supremacy. I was raised by Chinese parents, and I felt all these pressures growing up. My mother was obsessed with me finding a wife, buying a house, and having children. My dad pressured me into career paths associated with economic success. At home they would get into screaming matches, but in public pretend we were a happy family. I was sent to therapy for a decade, while my parents did fucking nothing to address their problems. They were the pinnacle of Mel's definition of monogamy, but I'm pretty damn sure it had nothing to do with white supremacy, because these attitudes have existed in China for hundreds—if not thousands—of years. A mixture of saving face, confuscian paternalism, and lowerclass trauma. By making white supremacy the primary cause of monogamy, Mel inadvertently deploys the noble savage trope, making other cultures seem more emancipatory than they are. I have Asian friends who can attest that our countries of origin are just as bad—if not worse—than white supremacist America. Countries where women and afabs are property to be married off, so they're no longer a drain on the family. Countries with deep histories of fascism and race purges, caste and class violence, religious authoritarianism, and elite male paternalism.

I think Mel is a great relationship counsellor, but an irresponsible scholar. They've done amazing work untangling themselves from white supremacist systems of control, but they've also universalised their experience of white supremacy and monogamy (a universalising tendency I see in a lot Americentric literature). The kinds of control mechanisms Mel sees in monogamy can result from any unequal society organised along hierarchical lines, whereby status is achieved through conformity. Conformity to the one true path doesn't just lead to excruciating relationships—it is a tool of class warfare, whether along lines of wealth, race, gender, or capacity. In an unequal society, conformity reproduces inequality. Rather than default to white supremacy, I wish Mel dived deeper into anarchy as an analytic tool, as well as a community-building tool. Something to trace one's trauma back to its cultural roots, rather than to hegemonic answers provided by authoritative experts.

This is a warm and approachable guide to polyamory, but I wish it were more sensitive to experiences outside of America, and more radical in its analysis of monogamy.

Excellent. This book is accessible, but doesn't shy away from more complex concepts. It has a strong representation of the full spectrum of polyam relationships and provides excellent advice and recommendations throughout for activities and journaling activities. I dislike somatic therapy in general so I didn't vibe with a good chunk, but that's solely my preference.

The chapter on compersion is easily one of the best I've seen. The separation of intellectual compersion from emotional compersion and erotic compersion was a helpful separation for me. I had really only considered emotional compersion when using the term. I also love the quadrants of intimacy and the focus the author places on platonic relationships throughout.

While this is unlikely to be the first book I recommend to folks on the topic, I will definitely be recommending it to others.

This was "Love in a F*cked up world" meets "Polysecure." I think it is a great book for teaching the basics of polyamory while also encouraging less partner-focused practice and more community building in abolitionist principles. Unlike Love in a F*cked up world there wasn't as much focus on the romance myth but rather our monogamy-centric culture. A lot of it was review for me personally - though I did really like the 4 quadrants on needs that your community meets, that was extremely useful for me. I also really enjoyed some of the reflection questions, and the somatic exercises. I wish all nonfiction books had somatic exercises, moments to just check in with your body as you're processing new and sometimes difficult material.

A few critiques - first, the author doesn't acknowledge her privileges as much. She does talk a bit about her own experiences and identities but I always appreciate when an author recognizes that they are navigating ENM space / relationships with privilege, especially as a white woman. I did appreciate that this book did highlight many Black feminist and indigenous practices, including historical non monogamous practices. But again, even though there is a history of non monogamous practice, it wasn't always ethical and sometimes contained many power dynamics that were oppressive within the relationships.

I appreciate that it was written accessibly but I do wonder if it's at the cost of being a bit vague at times. She speaks a lot about having compassion, empathy, etc and I wonder if that is something useful to other people, whereas I find it more useful to focus on concrete practices (which the book does still name).

Still glad I read the book because I did get one helpful concept out of it as I named before, and it at least confirmed some of the things I already knew and continued to give me more language around it. Not a particularly mind-blowing book but an affirming read :)

Radical Relating has been added to a list of books I highly recommend for non monogamy/polyamory. Mel Cassidy doesn’t just touch on deeper topics, but REALLY gets far in there. I’m truly not a big reader and it can take me a while to get through books even that I’m enjoying — but I can honestly say that I didn’t want to put this book down.

I’m very fond of Cassidy’s work overall and was excited for this to be released. The somatic pauses and journaling prompts throughout were a lovely touch and I could feel the calmness while reading.

Much of this book goes well beyond Polyamory 101 level. Breaking free of mono-normativity and incorporating anarchy along with queerness are topics that could benefit all and not only those interested in or already practicing non monogamy. I feel Cassidy’s book should be on all polyamory must read lists.

One of the better books on nonmonogamy I’ve read. It takes a different cultural approach as compared to psychological (Polysecure) or lived experience (Open).

Book Review: Radical Relating: A Queer and Polyamory-Informed Guide to Love Beyond the Myth of Monogamy by Mel Cassidy
Rating: 4.9/5

A Revolutionary Blueprint for Post-Monogamous Love
Mel Cassidy’s Radical Relating is a seismic shift in relationship literature—a trauma-informed, somatically grounded manifesto that dismantles the “monogamy mandate” while offering tangible tools for building liberated connections. Unlike conventional polyamory guides focused on logistics, Cassidy interrogates how capitalism, colonialism, and patriarchy infect even alternative relationships, urging readers to “re-wild the ways we love” through queer and anarchist frameworks.

As someone aware of both monogamous and non-monogamous dynamics, I was struck by Cassidy’s unflinching analysis of how “internalized mono-normativity” breeds relational trauma, particularly their somatic exercises for tracking bodily responses to jealousy or insecurity. The Relational Ecology Mapping exercise (a standout tool) helped me visualize relationship connections as a living ecosystem rather than a hierarchy, sparking profound self-awareness.

Cassidy’s prose balances academic rigor with radical tenderness. Their critique of the relationship escalator (the assumption that partnerships must progress toward cohabitation/marriage) resonated deeply, as did their call to center “communities of care” over dyadic coupling. The glossary of polyamory terms—from compersion to relationship anarchy—is invaluable for newcomers and seasoned practitioners alike.

Constructive Criticism
While the book excels in theory, some practical sections (e.g., the Four Quadrants Model) could benefit from more case studies to illustrate real-world applications. Additionally, the intersectional lens, though robust, occasionally sidelines class disparities in access to non-monogamous communities. A future edition might explore how economic precarity impacts relational freedom.

Summary Takeaways:
- The Bell Hooks of polyamory—a feminist, decolonial masterclass in loving beyond ownership.
- Somatic meets subversive: Cassidy turns jealousy into a roadmap for collective healing.
- For readers who’ve asked: Why does non-monogamy still feel oppressive? This book holds answers.
- A trauma-informed compass for navigating love after monogamy’s collapse.
- Queer, anarchist, and unapologetically messy—the antidote to ‘poly bro’ culture.

Gratitude
Thank you to Edelweiss and North Atlantic Books for the advance copy. Cassidy’s work is a beacon for those reorienting to a new map for relating—one where autonomy and intimacy aren’t mutually exclusive.

Final Verdict: A visionary, intersectional guide that transcends the polyamory genre. Essential for therapists, activists, and anyone craving relationships rooted in equity over escalators.

Why Read It? To discover how radical relating begins not with rules—but with dismantling the systems in our bodies and beds.

As someone with a large platform in the polyamory education space (Decolonizing Love), I approached this book with cautious interest. Many people have asked for my thoughts, especially given the author's visibility and influence in the non-monogamy community.

I want to be transparent that my perspective is shaped by direct experiences with the author over the course of several years. These include repeated unsolicited critiques of my work, boundary-crossing communication even after clear requests to disengage, and public posts that closely mirrored my educational content, sometimes shortly after those ideas were dismissed in shared spaces.

At one point, the author participated in a coordinated attempt by several content creators to impose a specific moral framework onto my work under the guise of "community accountability." My requests for space and respectful disengagement were ignored, and the situation eventually escalated into personal attacks and a video that named and misrepresented me in ways I found harmful and disingenuous.

What complicates my response to this book is that it uses a vocabulary I once had hope for: radical relational ethics, somatics, anti-oppression language, but in a way that now reads as performance rather than embodied practice. Knowing what I know about the author's offline behavior, the content feels hollow, even when some points appear technically correct.

This review isn’t written lightly. I believe in accountability, and I also believe that if we’re going to explore transformative justice or community care, we need to model the values we claim to teach. I cannot recommend this book or the author’s broader work in good conscience, especially to readers seeking integrity in both theory and practice.

This book is one of the best books on alternative relationships and non-monogamy I have read. I would highly recommend it to anyone wanting to explore relationships in ways that differ from Western societal expectations. It's not a book about opening up a monogamous relationship, it is an alternative way to explore the experience of relating to one or more people.

As others have commented, the relationship landscape divided up into four relational quadrants is quite helpful as an alternative to monogamous relationship models.

The chapter on compersion (finding joy in your partner's excitement, love or experiences with someone other than you) validated that it is not always easy to be joyful in your partner's experience with another. It takes a realistic look at the dark fears we might have about the security of our relationships and offers ways to navigate complex relational landscapes.

I also found the chapter on communicating and working through conflict (chapter 19) particularly helpful. You don't have to be non-monogamous or queer to appreciate this book. In fact, if you are monogamous and you read only chapter 19, you could really be doing yourself a favour when it comes to relationship conflicts. But it would be even more helpful to read the whole thing.

I awaited this book with bated breath for a very long time. After having attended several courses, workshops, and coaching sessions with the author, I was keen to have a reference material, in their own words, that I could both re-read and reference.

Radical Relating exceeded my expectations - and reshaped them. A term that came to mind in reading Radical Relating was "self-interactive" as there were many opportunities to explore and connect with myself in new ways throughout the book.

There are few books that are as deep as they are accessible and this is one of them. If you're new to non-monogamy or interested in new ways to see it and yourself, this is a great resource.

One thing that struck me was how the mood of the writing fit the nature of the topic: If the topic was serious or reflective, the book felt slower, deliberate, and open. When the content was curious or joyful, I read it faster with a smile. I have read a number of "self-help" books and not many have brought my feelings along through the pages.

A poly book that focuses more on reimaging our relationships. Definitely some concrete steps and thoughts but less about the what to do and more on reforming our thoughts beyond monogamy. I especially appreciated the look at relationships beyond just the romantic and sexual.
