Anita1234,
Welcome, I'm relatively new to the board. I am divorced from an alcoholic but also the mother of a heroin addict.
If you don't have children yet, I'd ponder very, very carefully if you want to continue in this relationship. There are few things worse than being married to an addict of any kind....having kids and being married is far far worse.
As you are take care of yourself, take time to step back and see things as they are.
