Thank you everyone for the responses. STBXAH and I are still living together because we haven't nailed down the terms of our divorce yet. I have been focusing on me and he on himself. There's been no questioning him on if he's going to meetings or nagging him when he smokes weed. We are both very sad about the splitting up, but have managed to keep things cordial...i.e., he goes to the grocery store and asks me if I need anything, etc. So perhaps I could see us being friends in the future. But again, I need to just focus on today.
