Girls are trained from a very young age to invent “cover stories” so that then they’re called “crazy” or “manipulative” instead of what you’re being called, which is “a bitch” too all your mutual friends.

Your friend didn’t want to get together either, she was just grumbling and psyching herself up to go thru with the damn thing and angry you had the self-regard to take care of your own needs. Envy. Lesson learned.
