“Will you go to AA with me when I get out? I said I would. ”
leaped out at me.
His recovery is HIS. I hope others with more AA experience will weigh in here: maybe a significant other might attend an occasional meeting, but recovery is not date night. If his recovery is predicted on your involvement, it’s not going to work.
He has to learn how to reshape his world and how he reacts to life events whether you’re a part of that life or not. He seems to want to assign his life over to others...the beer every other day guy, the new hire who found the rehab, you to drive him there and then go to his meetings with him.
Be careful, yes? You have come a long way. No need to travel that road again.
Wishing you well...
