You should be proud of yourself for doing whats good for you. As difficult as it was for you to take a stand on this doing it now was a wise decision.
I've been married to an alcoholic for 9 years. I sometimes wonder what would have happened if I had taken a stand at the beginning instead of letting things slide year after year.
I hope he will get some kind of help but if he doesn't remember that it is not because of anything you did or failed to do. Recovery doesn't happen until they want it bad enough.
good luck
