This evening I was returning a call to an aa member and it became obvious to me that she was lying about being on the way out and then she contacted me to say she was at a meeting. I know she is drinking and relapsing. I am very fond of this lady and she has a good heart but I had to stop myself from sending a bitchy text. It makes me so sad.
I am glad you didn't send a text like that. You can only control your own sobriety. It's her call if she wants to drink again. And unless you are a mind reader how could you "know" for sure?
Even when I have 'hard evidence' that someone has relapsed, or when a former sponsee admits to me himself that he has relapsed, the right thing for me to do is simply let him know that I care what happens to him and let him know that, if he survives the relapse long enough to eventually want to try to get sober again, he knows how to find AA and he knows how to reach me, and I'll be more than happy to take him to a meeting again. There is really nothing more that I can say or do beyond that.
