I believe that doctors do have some sort of obligation to report if someone is being abused, or is a danger to themselves or others. That probably differs from state to state - I don't know Ohio law.

If you're getting beaten up, why...? I know it's easier said than done, for a lot of reasons, but...nobody deserves to get beaten, ever. Been there, not doing it again. Get help and get out, if you can. Let your doctor help you - they know about resources we might not find on our own.
