Thought this might be a helpful list, though I know it's not as long as others who have posted (and not necessarily in order):
Divorce Busting, Divorce Remedy , both by M.W.D. I found Divorce Remedy a little more helpful. I think I just like the image of "remedying" something better than "busting" it!
Change Your Life and Everyone In It! also by M.W.D. More of a DR approach to other relationships (family, friends, professional colleagues, etc.). I believe this came out before DB/DR.
Women Men Love; Women Men Leave. Don't waste your time on this one. Not at all helpful.
Real Magic: Creating Miracles in Everyday Life, Dr. Wayne Dyer. Excellent resource. His principles fit very well with DR and take things to another level. Jungian based psychology blended with eastern philosophy and religion. One I will pick up again!
The Notebook , Nicholas Sparks (fiction). An excellent book to read if you're needing an infusion of hope.
Men are from Mars, Women are from Venus , John Gray. A pop-psychology book that boils down the thought process and communication difference between men and women. I find this to be a handy reference guide and one SO and I plan on utilizing more together.
The Five Love Languages , Gary Chapman. Good general reference for learning how people hear and receive love differently. Worth a read; don't let the drippy Christian references be off-putting.
Feeling Good: The New Mood Therapy, David Burns. Excellent, life-altering reference for me.
On deck to read together with SO is The Lost Art of Listening. We are both anxious to spend some time reading together, and he had a book he wanted to do as well, so I let him go first! This was one of the easy ways I could choose happy over right -- his book is no less important than mine, so it can wait. He's happy we're doing his book, and I'm happy he's happy. Works!
