Has your W ever given you any indication that she wants to reconcile?
Unfortunately she has. And I say unfortunately because I still beat myself up about all the bad decisions I made when she was still trying. After she revealed her affair (over a year ago now), she was remorseful. She told me she didn't want to end the marriage or break up the family and that she had a lot of "work" (in the IC sense) to do. Things got better but then got worse and by the end of October she was suggesting that I should move out. Bear in mind that she met OM2 right around this same time.
Most of the people I talk to tell me that there was nothing I could have done. That she had made up her mind a long ago and was just dragging it out and working up the courage to deal with the guilt. But I still regret all the spying, begging, crying, and convincing that I tried to do during the first 3 months after BD. If she was still on the fence, I'm sure my behavior helped to push her to the side of leaving.
