Like fb said, keep on doing the work on your side of the street. That work will never be wasted, regardless of what the future holds. Please don't make the mistake of thinking that if he gets and stays sober (a big IF), it will solve all your problems. I thought that way myself and delayed getting to work on my own recovery b/c of it. When things went south, I had no foundation to support me and had to start from scratch. Build your foundation now--it will stand you in good stead no matter what.
Wishing you strength and clarity.
