Only a few short comments on that subject if and when ABF brings it up himself, otherwise I keep my thoughts to myself or on this site.
Just now I have gut feeling that he is getting toey, that a breakout could easily be ahead. I am trying to decide whether to ask if cravings or a trigger are causing concern, or just keep my mouth shut and hope it is just indigestion on my part. He said last time he was sobering up, for me to let him know if I was worried and he would tell me honestly if he was having a problem, but things change later when completely sober, so I am a bit wary of rocking the boat.
If he does hit the drink, from past experience it could be a rough ride, and staying detached would be hard as we live in the same complex, but being prepared is some help.
God bless
