Your boyfriend doesn't sound like all that nice of a guy. If you were in some kind of a real jam, you might find that your parents care a lot more about you than he does.

When he talks insultingly about your parents, he is testing your willingness to put up with that kind of talk. He is a controlling guy. He knows that, if he can undermine any loyalty you have to your parents, then all your loyalty will go to him. That's not normal, healthy thinking. Some day you are going to find out that this guy is not the great catch you think he is.
