Thanks, Cher

Thank you for the positive support!
The problem with this guy is that we were friends for a long time, and we live together. I've already told him (and my other roommate) that I'm going to get a place on my own when our lease ends, in August. I've already become much more social and directed and positive and self-supportive in my life. I'm surrounding myself with positivity. I just worry that I'll fall back into an old script or role, since I've known him a long time. But then I tell myself, "You will not forget. And he is just a person; you can ignore him. No big deal. He doesn't have power over your life." What do you say?
