He beats you? Report him. I know he's your father but he has no right to beat you. Maybe you should tell him to stop that and move with a relative or close friend for a while. Tell him to back off. You want your privacy and you're just not getting enough. Thats not fair. Tell him that of course, he can be protective but not over protective. Maybe you should stop telling him where you're going and if he asks, just lie about it for a while. Just for a while.
Good luck.

You've tried to gain my trust,
talking is not enough. Actions speak louder than words;
You have to show me something.
