You know what, he may be a master manipulator. I think cheating on your wife, you almost have to be. In any case, I KNOW he is a good person at heart. He might feel great sexually with the OW but he probably doesn't feel too good about himself as far as his wife and kids are concerned.
I really can empathize with him. He THINKS that he loves this girl although he cannot fathom giving up all that he has for her.
Jokerman, I have to admit that I used your words on him. I said, "she has NOTHING to lose by going after a married man with three small kids, you on the other hand have EVERYTHING to lose, including your kids." I am starting to think that these are the words that actually hit home for him.
If he as to "see" her a few more times to end it, I totally understand. He is a sweet and caring person. That is one of the qualities that attracted me to him in the first place.
How long I can be this wonderful, compassionate and caring person, only time will tell. In the meantime, remind me now and again why I am doing this, will ya?
