Confused, I remember when the addict in my life went clean for a few months. Then she relapsed. On her wedding day. It was horrible trying to get her in her wedding dress and help her with her make-up while she was drooling. She had to be driven to her own wedding because her license had been revoked and her car had been totaled. She had fallen asleep at the wheel and went through a stoplight.
Recovery is a process. It doesn't just "happen". There is a lot of wisdom in those that say to wait at least a year before making any major changes.
BTW, although my addict never abused alcohol, I found a lot of comfort in Al-Anon. As mentioned above, the pool of members is larger so you are likely to find someone in a similar situation. Also, over time I discovered the similarities instead of the differences. That is not to say there are not "toxic" groups, because there are. Keep looking, hit different meetings. That's what I did and it made a world of difference.
Sending good thoughts your way.
