Ok, new update... He agreed to got to a different rehab where a friend of his works and is very supportive. Of course he agreed to this only after he finally realized we were not softening on our bottom lines and he would be home/job/phone/car-less as of today no matter what he decides.
His dad's supposed to get him on the bus for the 6 hour ride to rehab at 2:30 today. Fingers crossed.
I have to say that there is a part of me that is so happy to be DONE with this madness. We are getting him into rehab which is well covered by insurance, but after this we are DONE. He is officially on his own. Just gotta keep my ex on the same page but he's doing so much better about it now. It was harder for him to let go of the dream, but he's getting it now.
