Katie, it sounds like you are already living without him, and doing a great job of keeping things together for you and your baby. I have dated addicts in the past, and one thing that kept me in those relationships was that I had this fantasy about what life could be like if the addict got clean. I also sometimes separated the addict's good qualities from their bad qualities and told myself that if I could just have the good part, I would be happy. It's important to remember that the good and the bad all come rolled into one package, and stay grounded in the reality of what the relationship is actually like and not what it could be like. Do you want to stay with the person he is right now?
