He was drinking and driving, got stopped and blames you? This sounds like a "him problem". If he is that arrogant to do something wrong and blame another person without taking any responsibility himself, we think it might be a good idea to let him cool off for a while. If he isn't going to write you, he's the one missing out. You are free to come and go, and since you can't visit - go about your life he doesn't sound worth it. If you ignore him, he will definitely try and make up, again.
