The letting go process for the WAS is a tough one. The previous suggestions seem extreme and nothing I would do and my husband was back with OW this weekend. He never saw the danger of just talking with her, my problem was the mail. She had paperwork he needed. Now after months of trying, counseling and work, I can't do it any longer. I can understand how hard it is for him, but what about the other side? Can you really make your spouse do all the proper things to cut all contact with OW? How do you make him do that?
I wish you all the best with your current situation.
