How do i break up?I told him its over and he wont let me go?

He lies all the time about where he is,i only see him once a week,he has hit me once very badly(i got in the hospital),he is a model and works pr at nightclubs(i hate that),i suspect he is a player.Plus we ve never had sex together even though he s not a virgin.He only wants bjs.He cries and begs and tells me im his everything etc.He keeps calling even though i dont pick it up.And he comes by my house.He always does that and in the end i take him back.How do i do it for good this time?In the past i had been trying to break up with him for two consecutive months,ignoring him,insulting him,not seeing him.we have been dating for 3 years.Why is he insisting?
