This is my first encounter with Dr. Leman's book. This book is easy and fun to read. Good sense of humour.
Some of the suggestions are practical (but not all of them). It's a good reminder.
I found this book somewhat bias in a sense Dr Leman stereotyped man being "quiet", with "few friends", only focus on physical connection. My husband is the exact opposite, he is the most extrovert, talkative person I have ever met. He has probably 10 times more friends than I do. I have other guy friends who are more extrovert. I guess Dr. Leman can only speak for himself, not all men are like him.
If you are looking for something leisure to read, this is a good choice. If this is the last resource to save your marriage, I think there are better suggestions out there.
Many of the tips in this book I was already doing, but it was a good reminder to do them out of love again instead of out of habit. Attitude can make a huge difference. If you are not already do his recommendations, though, you really should for a healthy/healthier marriage. Basic ideas to put your spouse first, like you did when you were dating & first married.
