No, you shouldn't.
If you are looking for permission to tell him good-bye, consider it given.
Get out before you get a permanent injury from this guy who claims to 'love' you. No matter how many times he claims to love you, if he bends your arm back hard enough, he will break it. Or he will do worse to you. Who cares how he treats other people? All that matters is how he treats you, and it's lousy.
You don't deserve this.
