Maybe she is starting to struggle with fitting in with the kids at school......or she is struggling with a choice or decision she has to make and can't tell anyone about it so she is taking it all out on the nearest target which she picked to be you. I would sit down and write her a heartfelt letter or note, in it asking her what is wrong and why she is treating you the way she is.........just remember to also tell her that you will always value the friendship that the two of you have had.

Hi i just want too say do you value her friendship as person? Or you do not care anymore? It seem your best friend is jealousy maybe she feel that you are going too replace her and never be friends with her again. Or the last reason it could be your friend is going through something badly then again this is akward behavior!

It happens to me sometimes for no reason, at all.If she continues to ignore u, then do the same to her, and see her reaction, she will probably feel the same.Other than that, think back about what u told her from before or something, she might have considered it offending , and got insulted. look, the best thing u can do is talk to her about, no matter how crazy it sounds.

Is it worth putting someone u love infornt ur mother

self check is good
