It's hard to get past infidelity. My wife only had an Internet affair and I'm having a really tough time getting past it. With the other stuff, the ex, the attraction to women...give yourself some time. Spend that holiday with your parents if they are supportive. Isolating is not good. You are not alone...

Move on...that's what I'm trying to do with my life. I find that if I isolate that I just get deeper into self-loathing. It's when i reach out to others that I am able to escape, even if it is just briefly.

Best wishes to you.
