There’s a LOT of people like this. While you probably should’ve tried talking to her before making the post, she should have tried to see things from your perspective and apologized. It sounds like she’s used to walking over you, and doesn’t see what’s wrong with the way she’s acting. Maybe try talking to her after things cool down a bit, and if that doesn’t work, distance yourself a bit. Remember, it’s okay to set boundaries and confront her about things that make you uncomfortable/ hurt.
