woow...ithink if he's not leaving you alone at all either yu shud tell your gf to talk 2 her parents OR you should talk to them WHEN he's at school.dont give up though kuz then your letting HIM win and your gona ruin a relationship that[apperently]]you dont wana lose.good luck! =]
dude go talk to him!!! ask him why he hates you so much, and tell him that he can't make all of his sisters decisions for her anymore...
