I signed up, to post in this thread. My wife cheated on me five years ago, with my best friend. It hurts more than you can believe. It takes time to heal the wounds. Talking and being there for him, is like a dressing on the wound. Be VERY open and forthcoming. You have completely betrayed his trust. A relationship is built on trust, so there are going to be a LOT of issues. But, if you can show that you are open, and loving, he will eventually come around. For me, there was always a nugget of fear, of her doing it again... and her leaving me. To this day, I still feel pain. It will never go away. That is not to say I have not been happy, but that little nugget has always been there.
