I remember those days!! Girls like that can be so annoying and frustrating, I understand because I've been there! I am guessing your in high school...? That is one of the BIGGEST reasons I hated high school, but I still graduated and got through it. My best advice would be to, ignore her. She's obviously jealous of you, or just has some pathetic reason for doing it. DON'T LET IT GET TO YOU! It will pass, and you'll wonder why you even cared about it. If she calls, don't answer, or hang up on her! It's seriously not worth your time to worry about what this girl has to say to you. Good Luck!
