My son had a similar argument -- he had $5000 in a savings account that his father had put aside for him. In his mind the money was "his" -- and it may have been in theory -- but there is no way in he** we were going to give him that money when there was NO indication whatsoever that it would be spent wisely.
Rule #1: Never give an addict cash.
You can tell him that it's not feasible to sell the truck right now and for all intents and purposes the money is simply tied up. That's life!
Don't make any promises about how/when he can get the money, because in reality it could be a year or more and there's a LOT of stuff that would have to happen first, right?
You can also say that you love him but the next phone call you want to receive from him is the one where he says he's ready for rehab... until then, don't bother.
Harsh, I know.
I'm sorry
