Keep reading and posting here. I know your pain, I've been there.
Don't move out of your house. Don't do it. Let her move out. You didn't cheat. And it's your house too so if you want to not appear pathetic to her please don't move out b/c she told you she is cheating and wants a divorce. Just say OK there's the door W and turn the TV back on.
Implement the Last Resort Technique:
1. Stop pursuing (none, zero, nada) 2. GAL (get a life) 3. Wait and See.
You need to get out and get busy and try to take your mind off of this, at least some of the time. Change your focus off of her and on to you. Make you and your life the best it can be.
I will check this later and post more then.

It is not things that bother us, but the stories we tell ourselves about things.
