What happend?

so i had this friend for about 7 yrs and we hung out together ! and there was this person in our school that we didnt really like she gossips blackmails and stuff !!! then one day my best friend started to say lots of mean stuff to me and i thought i...

must of done something wrong so i just said sorry to her. she just ignored me and later i found out she was hangin out with that person we hated! they would both make fun of me! how could she do this? i was with her for 7 whole years!!!!! do people change that fast?

Maybe she didn't change, she was lying to someone either you or the other girl, maybe this is who she's been all along and it took this long for her to show you her true colors

OR maybe she's just pissed off about something and the EASIET things for her to do was turn against you. Maybe try sitting down with her and having a real good chat, and if she won't even listen to you, then she's not much of a friend, no matter how many years she was.
