I wanted the email written in his words, not mine. He informed her he has no desire to have any communication whatsoever with her, that any contact at all with severely damage his relationship with me and our family. He told her that he has made his choice to love his wife and children as he should. He told her that I will be checking text message records and that I have total access to his email account. All passwords from his phone and computer have been removed. He also told her that if she emails him, it will go directly to his "trash" folder and be deleted. He sent the email to me and to her, so she knows I'm aware of this. Today is the day her divorce is supposed to be final, so I think it sends a clear message to her that even though she is now legally available (not that it really made a difference to her beforehand), that he is not interested. She needs to move on and never contact him again.

I believe that my husband really wants to move on and heal with me and our family. He told me he wants to rebuild our lives. I believe his heart is in the right place. However, I also believe he is weak sometimes, that he was addicted to the "high" emailing and texting with her gave him, and that he has slipped. If I've told him once I've told him a million times, if she is what you want, GO GET HER and let me move on with my life. I did the begging thing for so many months with him, and then I just decided to let him go, that if he really thought she could give him such a better life than I could, then to knock himself out. That is the attitude I obtained when he filed for divorce. I completely shut down, no contacting him, and I only answered questions about the kids when he contacted me. I kicked him out of the house, and he wasn't allowed to move back in until he dropped the divorce. He knows that if this happens again, that's where he will wind up again. I think he can tell I mean it this time; that I've truly had more than enough and am losing my interest in fighting for this.
I appreciate all the advice I have been given here. It has helped give me strength for setting boundaries with him. My heart has a lot of healing to do, and I'm hoping in time I can begin to trust again.
