My advice would be to break it off and let him focus on his sobriety and you focus on you. Living with an addict and a recovering addict isn’t easy. Is there any kids involved?
This isn’t harsh by any means and it’s tiugh to give more advice with any background info. All I know is that sometimes the best thing you can do to help an addict is detach with love. Remember to put yourself first. There’s really nothing you can do to help him. He had to help himself. Is he ready? Does he want it or is he just going it because it is court ordered?
