Stabbed from the back..

Oh wow, that's crazy. I would feel totally betrayed. It wouldn't be as bad if it was someone else that your wife had an affair with, but your own flesh and blood? That just makes things worst. Your brother should have known better. I wouldn't be able to look them in the face without having some violent thoughts. As for the child, I really hope that you won't cut them off completely. The child is an innocent party and none of this is really their fault. Your relationship might get a bit rocky because you probably wouldn't want anything to do with the kid since he/she is not yours but I think you should still be a part of their life. I actually know some men who went through something like this and they still considered and raised the child as their own. In my eyes, that makes them a really great person.

I am a woman but I would imagine that this, being the worst type of betrayal, would be the most painful and humiliating experience a man could ever experience and the hurt that the knowledge that his own brother played a huge part in this would be too much to bear. If I were a man in such a situation I doubt that anything would ever repair the damage to the relationship and I would walk out permanently. Another painful aspect of a situation like this would be the child concerned because the betrayed man would know and love this child as his own and yet every time he would look at the kid he or she would remind him of the worst deception of his life.
