Given how much he has tended to rely on his parents and you to do the heavy lifting for him in getting him treatment, this seems like a set up, conscious or not. If he takes you with him to three meetings in a day with a bunch of driving in between, that's a long tedious day, so see, how can anyone expect him to do this? Maybe you'll call the probation guy for him and get him out of some of it?
Not saying you would, but there's something that doesn't feel right here. He may be accepting this as punishment, more or less, but that's not the same as being open to the recovery process?
This is only supposition, of course...but recovery really isn't a date night kind of group activity. My husband and I talk about everything, but when I quit drinking this time I didn't say anything to him for months because I knew I had to do this on my own.
Hope things go well for you...
