Codependent No More: How to Stop Controlling Others and Start Caring for Yourself by Melody Beattie
The particular sections that were very helpful were on detachment and just the general theme that you cannot control people or force people to do things. The book does have some focus of being a codependent of an alcoholic but in our situations you can pretty much substitute spouse in an affair or any other problem. Definitely a worthwhile read and in a lot of ways pertinent to most of our situations.
