Do i hate them because?

Well my crush had a gf and i didnt like her i found her odd... She is really tall, flirts and flirted with her bfs best friend and at lunchtime i was washing my hands in the toilets (lol i used the sink) while my friend was talking to me she asked what are you doin in here? Haha shes a creep and he had another gf i dont like and shes also odd she goes up to me and my friend and says why do you ignore me? She stalked us too and goes boo and she got one of her other friends to freak us out. A girl thinks i hate them because they went out with my crush... Do you think that too? I admitt i didnt like the 1st one i mentioned because she flirted with my crushes best friend i find that slaggish and mean to him because thats his friend and hes not goin out with her. Atm he has no gf so i dont hate anyone lol he had anothee gf but i like her shes nice.. Thanks i just want to know if you think i hate them because they were his gf or because their creeps lol ;)
