Hey, OP. I feel you, bro, I've been divorced twice. Some good advice in this thread, definitely get into some couples therapy. With a kid in the mix, you want to be able to tell yourself, and eventually the child, that you did ALL you could to make the marriage work. If it doesn't, at least you earned your way out. The cheating is always difficult to deal with; it's cliche to say it's a symptom of other underlying issues, but it sounds like it could be what's going on in your case. I'm here to say that there is life after divorce, as difficult as it was I've never been happier than I am now. My kid's mom and I get along better than we ever have, we're really good co-parents and we always get comments regarding that. Hang in there, my friend, because either way it goes there are really bright times ahead...
