I feel that I don't have best friends anymore?

So its summer vacation for me. Lately I haven't been talking to my "best friends". Keily and Corrina are 2 of the closest and since ive been "playing" guys they don't talk to me after the end of school. Leslie is know a bitc^ and talks shi^ behind every ones back. Then Carly has summer school. Kayla keeps complaining im super pretty and shes fat. Those are all of the girls. They all said there jealous of me. Is that why???? All my guy friends are still super close. I don't know what to do. If im too pretty then what can i do???
