I dont see where the two have anything to do with one another. If your marriage only transpired in the walls of AA then you might have a point. But he is your husband not an anonymous member of AA that you happen to know and your life transpires outside of those walls. these are the facts of your marriage not some private details you heard in an AA meeting so I see absolutely nothing wrong with them being a part of your divorce. If you still feel concerned then maybe you should bring this up in your Al-Anon meeting or contact someone at AA and get their blessing. I know its not the same but I kind of equate it to when i went to the church for a blessing on divorce - its not that i couldnt do it without their blessing but i felt at peace knowing that I had it.
