Wow. Very impressive for a newcomer. Good on you for going to a meeting. Normally the newcomer posts make my head explode.
Just as an FYI, with alcoholism every single day is the day the other shoe can drop. Their sobriety really is, as cliche' as it may sound, one day at a time. Therefore, you need to find whatever it is that works for you to not worry about that shoe.
For some people, that's breaking up with their alcoholic. For others like myself that's learning to detach with love and going to a lot of Al-Anon meetings (and hanging out here). There may be other solutions as well-- I just don't know what they are.
Good luck!
