I know how difficult your decisions are. I let my son come home early from program ( the same saying "whats two more weeks". What I have learned from his behaviour if he really wanted to participate in the program and get clean then he would have stayed. The last time he left we closed the door on him the hardest thing I have ever done in my life. The truth is as parents we all fear death. What I ask myself now if I allow him in my home as an active user and he OD'S I would never forgive myself, If He dies elsewhere I would feel terrible. Remember you can not control this, it is way beyond our control. There isnt a day that goes by I have to remind myself that his HP will guide him. He still calls to let me know he is okay. I wish there was magical answers to all of this, but it soley up to them. Prayers to you and your son.
