"Emotional Infidelity: How to Affair-Proof Your Marriage" by Gary Neuman was one that helped us a lot.
Granted, I was a little put off by the title at first pass. I don't think that anything is 100% disaster proof, but his advice and message helped us gain better perspective.
If you're looking for personal healing, I highly recommend anything by Pema Chodron. "When Things Fall Apart" is an excellent start.Me: BW 34

For last year's words belong to last year's language
And next year's words await another voice.
And to make an end is to make a beginning. - T.S. Eliot
