It is difficult to say with little or no 'feedback' from your h. That I believe is very selfish behavior. Either way, you have to proceed with the reality of things right now. Mine married the ow, therefore, he is out of my life forever and always as far as I'm concerned. I think he attempted contact today. I got a hang up phone call from a number in the town where his business is located 2 hours away.
I had to decide what the reality was for me and operate from that point. Without considering what he may or may not do. I don't want to deal with his hurt or confusion. He didn't want to deal with mine or my teens then...if he finds that he made a mistake...he'll have to deal with that w/o my help as well. He is a big boy who needs to find his own way.
I truly don't know about your h. I know that I don't want to ever hear from mine again. This is based on our entire relationship, not just his marriage to ow. He is not friendship material. You may need to decide about your h by looking within yourself.
