I know when I quit drinking and using, a lot of the relationships in my life warranted a second look once I had a clear head. I had to make a lot of changes in my life to get where I am.
The good thing is, you don't 'need' him to get it.. he wont get it, and that's just the way it is. I hope you're getting some other outside support, though, are you going to meetings or seeing a counselor or anything like that?
