i dont understand....

i'm still in love with my boyfriend and he is my first boyfriend. but he told his friends to call and threaten my brother after i said not to. he told them to jump him at the mall this saturday. it really hurts me to hear about that but my bf is denying all of it. he said his friends are lying to me b/c they dont like me. i cant date him much longer, my family will make me break up with him. how do i break up with him, everytime i try he starts crying and like guilts me into not doing it!
