How can I stand up to this b**ch?

I fell out with this girl because it don't feel right being around youths her and her friends are 17 and 20. She thinks she can control everyone and make them feel down I hate her so much. When I told her it don't feel right hanging out with youths her and her friends kicked off at me saying I act younger than them and use to bum them i said i hang out with new friends and they said randomly stopped hanging with them after all they wrote to me on facebook and twitter they seriously thought t with them again. The girl said to me the other day are they still coming up mine because my parents are away i said no im not allowed people up. Cant believe she asked me after all she said to me. How should I stand up to her?

Sounds like the two of you are in a battle for control over the situation. You are supposedly the older and more mature person, so why even bother responding to her? Un-friend her and have no further contact.
