I don't think I could have said it any better than PBJandPICKLES - your spunky post made me laugh. All I will say is, your husband and this woman are cruel, especially the way she writes and tells you what they do.

If I were you, I would pack up all those letters and deliver them to her hubby. He doesn't acknowledge your pain and bails when confronted with reality. I honestly doubt marriage counseling would help. I think you should let him go - you can still let him be in your child's life for your childs sake.
