Boyfriend and I live together at my parents house...?

He moved in with me a month into our relationship. Everything was great up until now. It's been 8 months. I am feeling smothered and disrespected a lot of the time. I love him very much but I feel like I can't catch a break. He doesn't pick up after himself. He can be controlling at times. He works full time but so does everyone else in the world. The one thing that I can not take now is that he addicted to pills and pot. I don't know what to do. I love him but I don't want to live with him anymore. I've attempted to get him out a few times but he does not take me serious. Any suggestions how to change the relationship to make it work living together or how to get him to take me serious about moving out of my parents house?
