I think that he won't be able to move forward until he is healed. I feel that drug addiction is a soul shattering event in life. To move forward, you not only have to get over the addiction, but get passed the root problems that lead to it. I have a cousin who was able to break free of it. He was a teen when he got into drugs and he's almost 40 years old now. But it took him multiple stints in prison as well as seeing friends die.

As for you, you need to take care of yourself, whatever that may be. He needs to find his road but no one can force him to it. But maybe if you work toward healing it will inspire him to also start working in that direction. Just a thought.
