If you have addressed the issue with him already, I would look at his reaction. Was angry that you questioned him? Or maybe he didn't even notice his behavior? Also, I agree with an earlier post saying that you should look at his friends. Perhaps his friends aren't really that great of "friends" in the first place. But are there times when he "slips" and treats you terribly? No matter what anyone posts , it is up to you to be objective. If it was your friends relationship , what would you tell her?
