Ok this is long but please read!
There is a girl in my friendship group (lets call her Louise) who everyone seems to trust and like a lot but I think i can see through her and thats shes not so nice and friendly underneath. She said nasty things about me to my face (in front of everyone) a while ago, but afterwards said she was 'joking' etc, even though she knew it hurt me. She also got a girl fired from her workplace through jealousy (because she flirted with her boyfriend who also worked there). She actually told me how she got her fired (her mum is the manager) and was very gleeful about it. I know shes not a very nice girl.
Just now I was looking on her myspace and saw that a bitchy girl who used to be in our year at college had added her...and it seems she added her JUST to get photos of our other friend (lets call her Natalie) from her. Louise had put a few pics of us at a club there, and one of them was of Natalie in an outfit that really didnt suit her. Shes quite overweight and doesnt dress that well for her size, but nobody ever says anything coz its not our place to. If she wants to wear it, whats the problem...sort of thing. Anyway, this girl who used to be in our college has always targeted Natalie and everyone knows this.
Louise commented on this girls profile saying thanks for the add etc, and the girl replied saying something like "hi..do you have any more pics of Natalie in that short skirt and stupid top etc...its just really funny...sorry lol" and instead of replying and telling her where to go (as i would have done, to stick up for my supposed best mate) Louise said "lol yeah i can look on my camera for you..." bearing in mind Natalie might see this comment when she looks later! And its not as if Louise even knows this girl that well, shes even slagged her off before!
Do you think that was out of order or am i reading into this too much? Should i trust this girl? I just dont want to be around her as i dont think shes as nice as she makes out. She seems to be out to either hurt people or help others hurt people...even her own friends.
