Morgandaisy, I also went to Al-Anon for several years (2nd ex-husband is an alcoholic) and A LOT of what they teach you applies here, but there are many many differences as well. Reading and re-reading the lessons (Understanding your partner's behaviors and Understanding your role in the relationship) helps.
It's a very complicated disorder and I'm trying to learn as much as I can about it. I've read several books that were suggested and am going to get more. I don't want HIS disorder to consume my world, but it certainly helps to know what I'm up against!
Keep posting and reading... . you'll find everyone here to be sympathetic and encouraging
