How do I become empowered enough?

I need to kick out my husband and his friend. It's been an abusive relationship, he's suffered many concussions from sports and work and he blacks out saying crazy shit. My family doesn't know that part, but the see me as a weak dumb ass for letting them destroy MY house. I paid for it, and the bills for the first year. I tried to kick him out and he began paying all the bills he's slacked on. It lasted 3 months. Then he invited his friend to move in without my permission. I need to kick them out. How do I grow some balls an do this? I'm so worn out and he's saved my life a few times. I truly can't see myself away from this, I think mentally I'm hooked, but I know I shouldn't be here.
