I'm going to call my best friend a dickhead for jokingly insulting and judging me.
Did their insults and judgments hurt you?
Even though I really like her and can't imagine life without her, she insulted me first.
If someone is your friend, especially your best friend like you're describing, you shouldn't call them rude names. Doing that will just make them feel bad and make them think you don't like them. You should be nice to your friends.
Well since she started it, I think I deserve the right to judge her. I don't want to be a push over.
An eye for an eye makes the whole world go blind. Just tell her you don't appreciate her judging you and to stop.
