Why is this girl still doing these things?

we have berated each other slandered each other and she has said some unfavorabvle things towards me and me to her,we have made racial undertones towards eaxch other(me being asian and her being iranian),but she will still want my attention.p by me and things of that nature and even get upset if i don't give her attention.I'm afraid that she keeps saying things behinf my back,but i've done my best to patch things up with her.(i was respectful the last few times around)but then i've ignored her ever since.Why would she keep trying?I don't trust her...but i'm confused by her actions.
