Thank you all for your quick answers! I went to lunch with him and brought up the car issue. He said 'I'm a bit floored by this - you sound like you're not going to be coming home for a long time.'
Where's the duck icon? I have spelled it out to him. I have been clear. It's really not my problem if he refuses to understand what I said yesterday : "After you've been totally sober and working on your stuff for a year, and you still want me, we'll talk about my moving back." Yesterday. He didn't say anything after that, but apparently that wasn't clear enough for him. I think I'm getting frustrated.
About the car: it's entirely in my name. I don't need it, we have a carshare program in town that would completely satisfy my requirements. Since my rent went up by so much, it actually makes a LOT of sense to sell the car.
I think I'll crunch the numbers and offer him to do a complete buyout. Thank you all so much!!
(Sorry about that annoying quacking noise.)
