Does she deserve my attention?

There's this one girl who, supposedly , is my best friend, and she says she hates X guy and Y guy. However she spends more time with them then with me, she's always mean to me, and instead she's sweet to them. She, sometimes, used to be really sweet with me, but nowadays she is just mean all the time, refuses to accept it. However she still calls me everyday and talks with me, and in school she doesn't give a f*ck about me.
She cried last week and I was the last one she talked to, and I was the one who had to approach her.. She has no reasons to not trust me, when I do have and still trust her..
