I can't lie I just wish he would call or e-mail and say "I am so sorry I was such a jerk. I have a major problem and I need help for it. I do love you and never stopped loving you. I am coming back to get myself better then once that happens maybe we could work on our marriage." Ok I know I'm dreaming but I can do that can't I?
Boy oh boy do I want that as well.
First you have to detach and that takes a while and then you can re -evaluate if that is REALLY TRULY what you want. If it is , then you can start working towards that. Remember you have no control whatsoever on your Hs situation. Look to your own future first. Everything else will follow.
