A friend of mine just got kicked out from his wife's house. Her name was on the lease, she asked him to leave. He said, "give me a month and I'll be out of here". The next day he made plans to leave, with no drama. Sometimes they are wrong, and you don't do people like that. You move on, and if life kicks their ass and you were always the best option but they weren't seeing it, they will have to take the chance you still want them.
You are similar boat in that you have to GAL as hard as you can and focus on yourself. You will take blows and damages to your psyche if you try to fit into the "same spot" that you did with your wife. Thats what happened to me.
GAL hard, and make sure your having lots of fun.
I'm loving the stories here about "affair bursting" and the wife comes home.
