No grand theories, just solid advice - and fun! This book is about creating a nurturing relationship, not a perfect one. It's practical, and there are a lot of different things to try. There is a handy index that lets you look up the problem you are having (anger, too much distance, resentment, etc), and it suggests which section of the book would help. It covers a wide range of issues, and gives a lot of creative ideas. My partner is somewhat couples-exercise-averse and she really liked it.
