Maybe you could ask your husband to ask around to his friends whether any of them have wives or partners in Al-Anon? When my first husband got sober, there was a bunch of us who all knew each other, and we did social activities together.
You could ask if he could get some phone numbers of any of those Al-Anon members for you. You could have one of them over to your house for coffee and a chat. That might be a way to find out where the best meetings are and maybe figure out a schedule once you've found one where you would fit in more comfortably.
