Fed up of my relationship

I'm at the point now where I don't even know if I want to be with my boyfriend. We keep having petty arguments that drives me INSANE! He has really bad temper and angry which causes him to lash out and basically scream at me and it's so uncomfortable, heartbreaking and embarrassing to be shouted at maybe at a public place. He's always been like that and I'm bored of it but I don't want to leave him.
