Instead of telling her she's been acting like a bitch, talk to her and find out why she's been acting like a bitch. That's what friends do.
People don't often act like tools without a reason, especially if that's not their normal behavior (and I'm assuming it's not, otherwise you wouldn't notice a difference). It's no more fun for her than it is for you. Something must be going on with her. Aggressive, rude behavior is typically a sign of stress or fear or depression.
I say approach her as a friend and ask her if everything is okay. If she presses you on why you're asking, you can say that she hasn't seemed herself lately. Otherwise, I would avoid specifically talking about her bad attitude, because if you start the conversation with a criticism, you will just make her defensive. Focus instead on how she's feeling and what might be bothering her.
Also, forget this "we" stuff. Speak for yourself and no one else. If your friends want to voice a complaint to her, they should do it themselves. Nobody wants to hear from one person that she represents a large angry caucus of dissatisfied friends. It's a vague and unfair tactic, and she will want to know which friends, why they're angry, what they said, and so on, which puts you right in the middle. Stay out of it. Speak for yourself, and do so with love, not condemnation.
I bet that's what you would want if the tables were turned.
"Something must be going on with her. Aggressive, rude behavior is typically a sign of stress or fear or depression." Yes, I agree. A little caring and compassion and attention from an understanding friend can go a long way in helping someone get past these things.
Great response! My friends recently attacked me for similar behavior of the friend that this girl is talking to. If she had been more sincere and caring rather than attacking, the issue would have been resolved a lot faster and I wouldn't have felt attacked in the first place. Sometimes, friends can take "acting out" behavior personally and see it as something personal when really it is just the way that the "bitch's" personal problems and dilemmas are being expressed and she cannot help that.
This is such an awesome, heart-warming response. Coming from someone who "hasn't seemed herself lately", her friend most likely already knows it and is working hard towards going back to her usual self. An understanding friend is a great gift under those circumstances.
I don't know but if it were me in your shoes, i would be straight up with her.
"Damn girl, why you acting like a BITCH?"
well this wont work because my friend is a mega bitch like she wont even listen to me she is like the kind of girl who teases you and she hits you too like i hate her soo much but its like i dont know someone help me out here....
