My partner is cutting my hair while I sleep

I've been with my partner for 12 years it hasn't been the happiest of relationships he can be very controlling and violent. I snore when I'm sleeping at night and he has started to bring scissors to bed and said he will cut my hair of if I do it again. There are no houses going in the area that I want and the only other thing to do is move back home and sleep in a single bed with my 2 kids
