Is she stealing my friend?

There is this new girl in my class and when she arrived she was by herself with no friends so I decided to be her friend and I did but.. then my best friend started talking to her alot and leaving me out. I thought well this cant be perminet just gvie it sometime. So I did but now they new girl isnt talking to me, ignoring me, only talking to my friend , disincluding me and I asked her if I did something wrong and she said no I am talking to you to. I said well you wernt looking at me or facing me. Then she rolled her eyes. :O My best friend seems to be spending too much time with her. What should I do?

You should understand that friendship isn't something that you own so it can't be stolen. Most people have more that one friend at once and don't compete for the attention they give each other. I suspect when she rolled her eyes she was thinking, "Why does this matter?'

Think about the difference between a friend and a competitor.

well then just tell her how u fell if my best friend waz doing that I would have said that u been with her to long wouldu about me and if she would have rollefd her eyes then just inore her cuz she thinks she is the coolest know
