kittencat, very sorry to hear about your Mom.
You can't stay there, you know? It's not safe. He will continue to hit you. Is there anywhere else you can go, friends? Family members? Even as a short term measure until you can get your own place.
If you have no where else to go, please call the Domestic Violence hotline and speak to them, they will be able to direct you to a shelter. They also have a lot of contacts and will also be able to advise you how to get out safely.
In the meantime, try to fly below the radar as much as possible. Don't argue with him, don't antagonize him. Keep your answers short and to the point if you must speak to him, "you may be right" "uh huh", "you might have a point there" - that kind of thing.
DV contact information is here:

If he gets violent, please call the police right away.
