I read this book for a book club and it probably isnt a book that I would have picked for myself but that's exactly the thing i like about book club! 
The reason I didn't care for this book was that most of the content was critical, how we are loving wrong, with very little helpful information about how we can improve our loving relationships. 
It was also extremely heteronormative with a lot of talk about the roles that men and women perform. It was clearly written with mostly an male audience in mind since all of the examples the author provides are from a male perspective, but since he spends so much time talking about the ways that men and women are different, it felt like he was never speaking to female perspective. 
He also completely dismissed heterosexual love which I obviously take issue with. 
There were lots of lines and observations that I liked! And it brought on really good discussion amongst our group, but I didnt love the reading experience, nor do I feel like I took away anything particularly profound from the book that has stuck with me.
