IB, I know its tough, but you are going to have to learn that you cannot change the way he does. I don't mean to sound harsh, but you cannot reason with this man. I have seen this a hundred times. He's going to run around with her to "show her off" to everyone and he's also going to act like a complete idiot as well. Best thing you can do is totally ignore him and not speak to him under any circumstances, as it won't do any good, because he's only going to see what he wants to see.
