Before I begin, I am not sure if this is the right area to post this, and I know I have asked some pretty stupid things in the past.
That being said. My "best friend" recently got a new job. I use to work with her, and we hang out all the time. Since she has gotten this new job, while I am happy for her, she has turned into a total bitch. She has started acting like she's hot shit, and it has kind of pushed me away. She keeps asking me what's wrong, and why I've been acting weird around her, and I haven't had the heart to tell her the real reason why.
Should I try to let it pass, or should I confront her on it. I am not the only one who is fed up with her new attitude, but I am the only one who would say something.
Again, sorry if this is in the wrong area.
