and now, I don't talk with her anymore

I can't believe what's happening! I don't talk with my best friend anymore. We promise that, we were going to a new school, we were going make new friends, but we were going to talk and be what we were. and now, yeah, she has new friends, but I also have new ones, but I can't forget my old friends. I think I'm not wrong, I meant she doesn't talk to me ANYMORE, sometimes, she just say hello to me with a hand, and never talk to me or stay with me just for while. On the bus, we are together, but, she is always texting with her new friends, and rarely talks. and when we arrive to school, she stays with her "new friends" and she didn't even say goodbye. and hurts, hurts a little, because, I think that I'm not "cool" or "pretty" or "skinny" enough to be her friend, so, I stoped to talk to her too, and now, we are like strangers, and it's sad, it's really sad. we promise a forever friendship, and now, I don't talk with her anymore...
