This is quite similar in style to Group. 
I liked it but there's not a lot of real self reflection. It's not a therapy memoir and it's not a book that outlines self improvement, but more like a storytelling with a very dynamic character. She gives the impression with a lot of choices she makes that she has very low ability to feel empathy- she needs to see consistent direct displays of other peoples flaws in order to think of them as a friend and not feel threatened. She seems to realize this in hindsight and describes it but doesn't make effort to change her perspective, only her actions, and only motivated because she keeps losing friends. 
We all want connection for selfish reasons but I find it really intriguing that she cares so little about understanding other people's minds when she's written two books like this about relationships.
I felt that way about group too, but in that one it was easy to see it was just a subpar therapist with slightly problematic strategies. This one felt more like a memoir by someone who hasn't been in therapy. Every little step in communication was pulling teeth. 
I wonder if people looking at my life from an outside perspective would feel that I'm so slow to learn and grow. (Not trying to sound mean, it's not a race and everyone is different. Plus we all start at different places and most growth just brings new challenges and weaknesses) 
It's easy to empathize with the author and I like the way she writes.
