I don't know what to do next, any advice?

I'm in a strange place at the moment, and I should probably define it before I take another step. I moved in with my ex a few days ago. I'm living with a man who for the past four years has taken me on a roller coaster ride of love and pain. Moments he loves me, at times he is a stranger I share a bed with. I've decided this will be the last time I live in this house. I'm struggling with what step to take next. Should I move in to a relatives until I can find a place? Should I stay here in the meantime just to avoid moving my stuff to my sister's where I know I'm not wanted? I want to stay here, it's my comfort zone. I want to be able to stay here until I've made my next move without him changing his mind and trying to talk me into being with him again. Since our last fight, we haven't spoken about what we're doing. He crossed the line and disrespected me and I've simply decided this is it. I don't know what he's thinking, or what he wants. I want to be happy. I want him out of my mind and heart for good. Even if he's still in my life. Maybe staying here is a way of disguising my hope for reconciliation. He hasn't asked me to leave, and he's sleeping on the couch. I don't want to talk until I've had time to think about what I really want. Has anyone been this confused?
