The feeling I had was that I was reading two books in one: one self-help, with insights that I, being just 21 years old and reading after a breakup (judge me), found very good; And another teen romance, with a shallow, juvenile and predictable story, which contradicts everything the self-help part preaches.
The protagonist, for example, is very difficult to like. Isabela is a spoiled and superficial 22-year-old girl, who doesn't need to worry about working, doesn't clean the house, climbs on other people's backs to get through college, is 100% straight-laced, has everything for free in life, stays in front of the mirror all afternoon and complains about futile little things. It seems her maturity stopped at 15 years old.
Also, all of the protagonist's relationships are ridiculously shallow and not very believable, probably because the characters have no depth. In general, everyone in the story lives according to Isabela - and 98% of their personality, which doesn't have to do with her, well, doesn't have to do with her, so it's not worth telling. It's as if the book - narrated by the blessed woman herself - only cared about the characters when they were useful to HER in HER problems. It's a narrative bubble without intrigue or twists. Not to mention that the protagonist's "evolution" doesn't exist, the girl just goes in circles, jumping from one frustrated relationship to another and in the end she doesn't even have a satisfactory outcome.
Don't get me wrong, the passages are fun to read and at times they are funny. I myself identified with a thousand events in the girl's life, but it really isn't a best seller.
Fortunately, the book alternates between this and beautifully written separate passages, which are insights and reflections on relationships, not just the romantic ones. It talks a lot about disappointments, overcoming, self-love, grief, healthy relationships and purposeless relationships that need an end. Personally, I found it quite therapeutic, after all I handpicked the book to help me with the phase I'm going through in my life. I admit that I highlighted and wrote down a lot of things, especially at the end, which talks about the title of the work, explaining what detachment actually is.
Having made all these comments, one of the interpretations I had is that, regardless of the practical aspects of life (studies, work, finances, experiences, customs, etc.), women have this little thing in common, which makes us very similar despite of our differences: the process of personal evolution in the face of bad relationships.
In my opinion, the book is worth reading and is very positive. To finish, I leave here one of the several phrases that I liked most from the book: She who loves herself is enough.
