90210, I was and I guess currently am in a similar situation. my boyfriend of 5 years has now been clean for a month from his heroin addiction. that may not be a long time but it's a start. like you said, you can't control his sobriety, but I have chosen to be there
for my boyfriend, as long as he is doing what he needs to do to stay clean. I'd like to think that if he relapsed I would choose to let him go, but I also know how incredibly hard that would be to do so. I can't tell you what to do, no one can, but I can tell you that faith will take you a longggg way in situations like this. whatever you decide, do what's best for you, because like you said, you have a long and promising life ahead of you as well. I hope this helps, just know anythingg is possible! =]
