My boyfriend said he’d kill me if I cheated on him?

I cheated on my boyfriend, but he said he’d bash me in the face with a baseball bat and then throw me into a wall and then kill me if I ever cheated on him. Then he would kill whoever I cheated on and then off himself. What do I do? he’s hit his ex for cheating on him before too. I’m too afraid to just break up with him.

For everyone calling me a slut or a whore, thanks. It really means a lot to me. I cheated on him before he said this and I did it because I didn’t feel any emotional connection to him. We don’t have love in our relationship. So no, it wasn’t the right thing to do, I’m aware. I was honestly just seeing if I wanted something else. Maybe I was a whore. So fucking what.
