I'm going to cut off my close friend/crush for talking to someone else.
Why would you cut off your close friend?
She asked out someone and I got jealous and passive-aggressive.
I don't think it's right for you to cut her off just for asking someone out. You should just have a chat with her about your issues. If she's your close friend then I'm sure she'll understand.
I'll talk to her. But I'm also mad that she's so quick to compare herself to other people. I've known her for a long time and it just pisses me off.
I think it is important to talk with your friend. She may not be aware of her behavior so you can try to help her out, in a respectful way.
