It' s very hard to live with someone when they don't understand addiction. Have you ever thought about going into a program? Maybe a detox first then a halfway house. I think it would be a great oppurtinity for you giving your living situation and it could help you learn how to stay clean and help you with many other aspects of your life and self. After that you could even go to a sober house.These are all steps to getting out on your own and learning to live clean. This is the only thing I can think of that may help you out of your situation. Please think about it, it can't hurt you.
With love and support!
