I'm so glad you are taking these steps. He'll probably figure out very quickly that the grass isn't greener w/OW. My only advise would be to set more boundaries. He probably shouldn't be coming over all the time--that just sounds like cake eating to me. I don't know, maybe I'm wrong, b/c I know how important time together is, but I just am disgusted at the fact that he is living w/OW. Keep setting boundaries and stay strong. It's sounds like you are coping well.
