My husband had a affair. He was 45 and she was 21. She is also married and has two kids. My husband and her kids got attached to each other. When I found out about it, I gave him a ultimatium. he still tried to keep it going even after. to this day I still don't trust him and everytime we fight i call him child molestor. He also took our son to the park with her and her son one day. Now my son has alot of emotional problems. I priase you for leaving him. I wish i could. No where to go.  tell the kids they are going to find out sooner or later. better to come from you
