Criminy. I really can not do much here other than shake my head here.
That is just the craziest story I have ever heard. Ok, one of the craziest.
You went out a second time with a guy that intended to do you harm the FIRST time? That is all I can say about anyone that encourages an alcoholic who is trying to quit, to drink.
Then you went out again and the guy that has told you he is in AA with time (yeah right) ordered a beer and you did not run right then?
Okay, well, this has nothing to do with AA. This has to do with you making poor choices and not being careful! I am sorry to be so harsh but I am truly scared for you if these are the choices you make. Please stick around, get support where you feel most comfortable and don't drink, no matter what!
