I read the title of your post, and my immediate response was:
I would go get a manicure and a pedicure, take a nice hot bubble bath and read something funny.
There was a time in my life when I would have been all entwined and entangled in my own A's mess and options and hearings and such. Today I know that the best thing I can do is get out of the way and let him experience his own consequences for his choices.
I don't know for sure, but I would imagine your A would not be the first person in that jail to go thru some alcohol withdrawl. If it got bad enough, they'd most likely call emergency medical personnel. My sponsor used to ask me this: what if THIS was the time he was going to hit his bottom and be ready to take his own action to get help, but YOU swooped in one more time to rescue him? I've read it here on SR, too.... you can actually love someone to death if you don't get out of the way.
Big hugs to you. I know it's hard... try to remember to keep the focus on you and what you can do for yourself today.
