Who could be bothered with someone like that?
Those kind of people are pains, and if they don't get their way all hell breaks loose. And even though she did the same thing to you, becuase she's "popular" she will expect you to fall at her feet, which, I would hope you didn't because that just destoys the principle of being friends!
GOOD LUCK, I hope it works out so that you're all happy again.
