It's not your job to be supportive of him. That's the job best left for professionals and his peer group. You are the one in need of support, especially at this point in time.
Thanks for the advice everyone. And outtolunch, I agree. I know rehab is not going to cure him of this problem. It seems to me that he is an emotional drug user that gets high when he feels overwhelmed. It's very hard to deal with, especially with my pregnancy hormones flying all over the place.
I can only hope that he learns coping skills and uses these tools to stay clean. As much as it would break my heart to leave him, I can't afford to stay in a relationship that's going nowhere when I have a baby to worry about. It's not easy. I guess I will have to see how things go when he gets out of treatment...
