I agree with Perna. You should get out of there as soon as possible. You need another shelter and then no one knows what can come up.
Speak as clearly as you can with your family, asking for their help and assistance.

You can substitute the habit of thinking about him and living with him with attention to how much your life will improve:
- you won't need to be scared anymore
- you can say as many things as you like cause no one will assault you
- your fridge can be completely empty and you can still have a big smile on your face

Remember yourself frequently how much better is your life WITHOUT him.
You might even want to write down all the bad things you had together and re-read them over day and day and say to yourself "lucky me I got out of there"
