Friend problem... :( :(?

okay so my bff and me hate this one person in are cl its just my bff always hangs with her but lately they been having "fights" and she really doesnt like that person. And I don't either. So this weekend we sended txt messages saying to that girl what I THINK. Because that girl thinks I'm one of her friends but at the same time I think she wants me to feel jealous because she hangs more with my bff. Anyways we send her txt messages all weekend. And then yesterday I ask my bff on the net if she answered back and she's like: I don't want to talk about it. So then I go on Nexopia (its like facebook) just chill like I usually do and I check the person I don't like's profile... And it says: Haha you have just been hacked by your one and only best ******* friend Natasha Blais (my bff) man I love you soo much, your the best you always make me smile, u'v changed so much since last year ur so pretty, don't leave me plz etc... and well Idk if my bff actually wrote that or if its just her
