confused

so there's this girl and we used to be bff's but now were not because she's friends with the queen bee and her group.The leader of the group a.k.a. queen bee is really mean to her sometimes like screams at her because of stupid things and then on friday she was supposed to go out for lunch with her but they ditched her so my friend who got ditched had to drive down the street with the vice principal to go get food.Than later I saw all of them laughing and chating.I'm really confused because she talks negatively about the queen bee with me and some other friends but when the queen bee is around she acts like she hates us.
