Just wanted to say that I can totally empathise with that feeling of "will they get sober without me?". That used to scare me. I used to hate the idea of him doing it because I thought it would prove to everyone that he was right, that it was me that caused his drinking. If he is what you say he is then id say its unlikely hes going to skip off into soberville and live an amazingly happy life because he's no longer with you.
