I'll start with the positives. I got this book because other reviewers said it humanizes people with BPD, which it does. It has a very hopeful outlook, which I appreciated. I did learn at least one useful thing. She suggests that when someone with BPD is in a state of self-loathing and saying excessively negative things about themselves, instead of contradicting them and saying they're not terrible and listing wonderful things about them, you should first validate that you understand why they would feel awful about themselves and that it's a reasonable emotion to have considering x, y, and z, but that still doesn't make them a bad person. Otherwise, they're less likely to listen because they don't think you *truly* understand how awful they are and how they view themselves, or think you do see and you're just being nice. Validating your loved one's feelings was obvious advice to me, but that's one situation I hadn't considered because I've always had high self-esteem and didn't think of that perspective even when trying to put myself in someone else's shoes, so I must thank Dr. Manning for that. It's a new tool in my interpersonal toolbox.
Now onto what I didn't like as much. She gives so much advice on how to communicate with a loved one with BPD and help them in various situations, but she doesn't pay enough attention to the needs of the other person in the relationship. She gives examples of how the behavior of someone with BPD may be frustrating, exhausting, or fear-inducing to their loved ones, but doesn't show how the loved one can communicate what *they* need out of the relationship, how they can get their needs met by that person, or how they can feel like an equal in the relationship instead of it being one-sided (if it isn't a parent-child relationship.) Which, if you're not fragilizing your loved one like she suggests you don't, is absolutely vital. She does suggest the other person validate and cheer-lead themselves, but that doesn't address unmet needs. Also, I was shocked there was only one page addressing abuse, and only in reference to childhood abuse. I feel like she put on rose-colored glasses and tried to write a positive and non-stigmatizing book by completely ignoring the abuse that can happen between someone with BPD and someone who loves them, in either direction. By doing so, she completely misses the opportunity to offer practical suggestions to address it in the most positive and productive way possible. Which is bizarre, because it's not like she's shying away from difficult subject matter. She has a whole chapter on addressing suicide attempts and suicidal behavior, and if anything I thought the personal examples of the behavior of a person with BPD were a bit too extreme and weren't balanced out by more mild examples. Which was another weakness of the book.
There were a few other things that bothered me on top of that. Some of the advice can be kind of vague, and while she gives very concrete personal stories, it's not always clear how to apply the principles she's laying out in other situations. One example that comes to mind of vague advice is a loved one using "wise mind" to find out if they did anything to violate their principles and whether their guilt is justified. She doesn't give enough concrete examples of when you actually *should* end a relationship with someone who has BPD, just telling the reader to make their own double-sided pro-con list. I'm okay with a book that suggests to be compassionate and err on the side of not ending the relationship, but not if it's not tempered by reality and concrete examples. I also, frankly, found it dangerous when she suggested in one sentence that it's best to call the police in the case of a loved one's suicide attempt without any discussion of the disproportionate violence faced by the mentally ill, people with disabilities, and people of color by the hands of the police, or any of the cases in which the police have shot suicidal people during suicide attempts. Especially since Dr. Manning actually lives in the United States. Calling the police is still the best option in many cases, but not discussing that was irresponsible on her part. And despite training with Dr. Linehan, there were some passages in the book that made me question the author's scientific accuracy in writing this, such as an analogy about how children in the Ukraine with smile at a kitten just as much as anyone in the world because it's an automatic response to emotion (this is demonstrably false; emotional responses are cultural and there are many cultures who don't smile to signify happiness the way Americans do), and another passage about the 12 step program (I don't remember where in the book or what it was.) Finally, and this is just a trifle, but I would have preferred her using the gender-neutral They in the book instead of switching back and forth between he and she, both to eliminate confusion on the part of the reader and to be inclusive of non-binary people. Perhaps she can do so in an updated edition, as well as fixing the dead URL links.
Overall, I feel like giving this book 2 stars because the negatives weigh so heavily, but there's such a crucial vacuum for a non-stigmatizing and humanizing book about BPD that I have to give her another star.
