Expanding, I'm so sorry that you're in pain. My ex filed for divorce (citing my drinking) and I immediately went to inpatient rehab hoping to save the relationship. He didn't stick around to see the amazing changes I've made in the last 7 months. Had he done so, it would have upset the status quo. See, when you were the "problem," your boyfriend could act any way he wanted. And because you felt guilty about drinking, you allowed it. You tolerated a lot more b.s. from him than you would now -- and he knows it. Your becoming well forces the mirror to turn around, and he doesn't want to look in it. There's a saying that "water seeks its own level." Your ex will continue to have unhealthy relationships because that's what he's comfortable with. You have grown and hopefully will demand more for yourself next time around. So while you are sad and you grieve, know that this is the right path.
