my bf doesn’t want it

So I am about 4 weeks pregnant, and I stopped my birth control (depo shot) because it was making me very depressed. My boyfriend knows this btw. We had sex and he ejaculated in me 3 times, knowing I was off birth control. I am ready for a baby and want it, but he is now saying it’s my fault and wants me to get an abortion. He also threatens to punch me in the stomach. what do I do?
