sooner,
On another thread, the idea of a "no think" weekend has come up. I think you might want one of those!

A lot of the questions you want answers to just don't have answers, and you end up using a lot of emotional energy trying to find answers. OW isn't worth the energy you are putting into worrying about her. So don't! Use the energy to build up yourself! I know you don't think he'll see it, but he will, over time. And you'll feel better, too!
