I can't say it any better than Tyrphanax. But for what it's worth, I agree. Addictions don't make for healthy relationships, and if he's not interested in changing, then you pay the price at least as heavily as he does. I have a friend at work, a woman who was in a relationship with another woman (ironic, no?) who was also my friend. But the latter had an alcohol problem as well that seriously hurt the sober one. The relationship ended painfully, but my coworker is much happier now. I'm not necessarily saying you should leave, but I'm at least saying that it's not healthy for you if no change is made. You shouldn't have to atone for his transgressions.
