Well, zonker,
You may well be right, but the only one whose drinking/using you can do something about is your own. You might want to check out an AA meeting. I'm in AA (sober 3 years) and it's the best thing I ever did for myself.
Who knows, maybe you will be an inspiration to your b/f. Might be tough, though, to get sober as long as you're living with someone else who's drinking/drugging. In that case, I think I'd do what I needed to do to get sober.
But that's me. Do you want the rest of your life to look like it's looking right now?
