I just recently learned that LOVE and NEED are two different things. I think I knew they were two different things, but I did not realize that I was confusing the two in my relationships.
I guess what I'm trying to say is....LOVE should be between two people who have their own lives separate from the other and do NOT NEED the other person to make them happy or a better person. Also, LOVE should not be about whether you NEED someone to complete your life or HELP you thru your addiction.
I think I am reading your post right and that he seems to think of you as his savior. Well...I am living proof, that kind of relationship/ need/ love does not work. I tried the be his savior thing and it did not work.
Let him work on himself and become whole and then you two can start to look at a future together.
