Let me see if I understand. You called, your husband masturbating to internet porn "cheating", yet you are having an emotional affair with another "REAL" man (by real I don't mean your husband isn't a man I mean that this new man is a real person not an actor in a porn movie or just a picture of a man) and your having this affair on the same internet that you caught him "cheating on you" on.
First of all, in my opinion, masturbating or looking at porn is not cheating! Second, having an emotional affair IS cheating.
Go ahead and leave your husband, whom you hardly see anyway you'll be doing him a favor. Go see how much better life is with this new guy. I'm sure he really is as nice and caring as he's making himself out to be on-line and not just trying to get into your pants.
I'm being a little sarcastic by the way.
