If HE doesn't want recovery, then no intervention, program, or rehab is going to do a lick of good. The best way for him to want recovery is to be so miserable that he is willing to do anything to get better. This is HIS problem to work out, not yours.
In the meantime, take care of yourself. Get to al-anon or nar-anon and get yourself better. That's the only thing over which you have any control.
