Should i still talk to him?

the jest- last nite my bf called me illegitimate,adding my dad sleeps with 2 or more women how did we know for sure? when i was 12 my father had an affair with another n it was a very disturbing experience for my entire family. when i told him,he got upset bout my not telling him before but now i see i shud never have.this is not the first time he's taunted me on it.apart from calling me names,now even this. ok i know i dont wana be with him n have clearly said so to him but he begged me to stay but still doesnt change.i was only tolerating it cuz he's having his finals n i dint wana spoil em.now shud still talk to him so that he studies n not spoil his grade or act selfish n just go away? he's put his profile picture as dat of a loser (i mean its a guy's caricature making an l on his forehead) n he called me 36 times last nite.but i could not talk to him so slept. wat do u think?
