when someone cheating on you... leave in silence. cuz every answer you'll hear it will be just an excuse for another chapter on cheating.
you're not stupid, but try to see beyond what's in front of you.
sorry for what happened.

You have to wonder what is it that makes him to turned on by this? Any explanation would be a good one (for you) but reality it isn't, if he's doing something you don't like and he's not planning on correcting it then you should leave because you're going to be miserable.
