There have been a lot of books on this topic, from the academic to pop culture books... even many magazine articles that have taken principles of social psychology to address why we fall in love with certain people, and how to use that. The author makes a point of saying on a number of occasions that this is not creating lasting love (that is a different topic), and that it depends upon a basic level of attraction and interest for any of this to work.
This book is witty, charming and extremely funny. As you listen to this book, you will find your head bobbing up and down and there will be a grin on your face because you KNOW what the author is talking about is the truth. It made me come face to face with the reality of things going on in my life and helped me to deal with these thing, because I was just too scared to face it nor to even think about it! If you want closure about things in your life, then this is the book to listen to!
