Yeah, that is always an interesting situation drinking in front of an A in social situations as you've described. I've been through that with AS, as well as A brother in law and sister in law. As part of their recovery and working the steps, they obvisouly will come into these situations at times and will deal with it as they see best.
I take the stance that I don't have the problem, so I'm not going to hide the fact that I like a drink now and then. If your AH is throwing it in your face, it sounds like he still has some work to do with his recovery. My ABIL told me once, while I was having a beer after we golfed, that HE is the one with the problem and if I want to have a beer, then have one, I don't have the problem. He said it was simple as that and if it turned into some kind of drunken party, then he would leave, but me having a beer or two wasn't a big deal.
Good luck with the snapping.
