Just had an argument!

So me and my boyfriend were talking over the phone this morning (long distance relationship) and he was talking about a chick from his school, he told me she was slutty and had sex with heaps of these guys and then he started comparing my tits to hers!! He claims he saw her tp on his mates phone which is probably true but anyways I went off at him and he said "your being such a bitch I'm actually not upto this right now" he's never called me a bitch or anything rude like that before but this seriously hurts my feelings
