Hey! It's been a while. I don't really do message boards much anymore, but I've got a sticky situation and I need some christian advice. I don't really know who to go to for it except here.

I want to try to make this story as simple as possible without being negative in any way, so here goes:

One of my best friend's is not a Christian. At some point about 2 years ago I introduced him to my Christian friends. He was immediately attracted to one of them who was, in fact, married. They started talking behind my back (behind everyone's back) and one thing led to another...
Anyway, It has come out now that they had an affair. Her marriage was already on the rocks and now she's separated from her husband. Her family and her husband's family don't want to have anything to do with my guy friend. Understandable. But he had been good friends with a lot of them and he's still my friend.
The other night him and I were hanging out and he was nearly in tears and said, "I know that what I did was wrong, but why am I the evil one and she's not?"
I didn't know what to say to him. I want him to know that God is love and will forgive anything, but the key people in his life that he looks to as examples of Christianity are refusing to have anything to do with him and have not forgiven him. And as much as I've been trying to bridge this gap, I'm watching him pull further away from ever knowing God and my Christian friends are pretending that he doesn't exist.

So what do I do? This whole situation is wearing me thin.
