If he wasn't willing to work on issues, then he isn't worth getting back. It sucks that he won't talk to you, but do the best you can. Move on. You're young, beautiful and have to wonderful children. Focus on that. Keep yourself busy and try not to think of it. Move on. What ifs get you nowhere.
Hugs and hugs and hugs, A.
