Let his new wife deal with it. But the only way I got through it was with counseling, medication and a supportive family. Even with that-I still had to do it myself, as your wife needs to. Have patience with her. She may still fear him and threats he has made.
Fear is very powerful and quite an obstacle to overcome.
In response to response to my wife's jerk ex. Thank you so much. I think you are right that she cannot rely on me to take him our of her life. She needs to find the strength to do that on her own. I am going to talk to her and tell her that she needs to learn to disengage in a conversation from him.
