yah, if a dude ever tried to hit you and you don't leave, and or stab him in the neck with a fork, thank you april, than shit's only going to get much much worse before they get better, if they ever do..
it usually goes from a simple round house to the face to the dude hiding out in the bushes with a knife or two and killing you and your "friend"..
run forest run, and don't look back.. but you won't, just like someone else has already said.. if you even have to ask the question of whether or not you should dump him, that right there tells me enough to know that you're not going anywhere, and that you enjoy being used as a punching bag.. for the life of me, i'll never understand people like you..
