You thing in this world there is a thing called RESPECT. It decided who is who. If a man KNEW I was married and slept with my wife, he is equally at fault. He has no respect for other men. I have NEVER went and talked to a guys girl, if I met a girl and asked if she had a boyfriend and she says yes, I kindly ease off and move on.
I would dump the girl in a second. Not of anger, but because that would totally **** up your trust, what she wants, etc. She is at fault, the other guy is at fault, everyone is. If she did it once what would that mean? She doesnt love you? Mistake that will happen again? Who knows. Not to mention you want to have sex with your WIFE after she ****ED another guy!??! NO THANKS.
I would not beat the guys ass. I would NEVER hit a girl. That is the immature thing to fight physically over ****. ***** boys start fights. More damage can be done mentally. If a **** wants to be a rude disrespectful ****, he will fail at life, and as I am moving on and living, he is stuck with no respect failing. Simple as that. As much as I would not want to hurt my wife, I am not the kind of guy to sit around and be walked on.
