Respectfully, you are trying to manage his recovery. That is never going to work. He will never have recovery unless he grabs it with both hands and he is the only person in the universe who can do that. He is an adult and only he can deal with this problem. Other addicts and recovery professionals may be able to help him but you cannot. You can love him and give him the respect of trusting him to deal with his own issues and that is about all. Perhaps you could put your energy into yourself because you are wasting it trying to make another person do what suits you. I wish you well.
