Sounds good. He didn't deserve a response. He is trying to get you angry and fighting so he feels justified in his rush to D. Good on you for getting out of the house and GALing with a friend.
You handled the staying over convo well also. He is clearly trying to cake-eat and you just won't let him have any of that. When he tries to fight, just don't engage him. Validate when you can, but not when he is acting like that.
If he wants a D, you can't control it, but let him do the work.
