um... because he has threatened to rape you, and beat you... That is why you might consider getting a restraining order. When he said "Even if I never empty it, it still remains true." He was implying that he does not intend to ever have you come back over anyway, so even if he never empties it, you still will never see it.
He is a jerk. This is simple. He intentionally is treating you very badly. I do question why you keep on insisting that you have a relationship with him. You are almost beginning to sound like a stalker yourself. He has very clearly communicated to you that he doesn't want a relationship with you. You really need to go find something better to spend your time on at this point.
