Go you!
100% agreed!
It seems “mean”, but what you just did was communicate and reinforce a boundary correctly.
You told her, “I do not tolerate being spoken to like that”, she pitched a hissy, and you didn’t tolerate it by calmly removing yourself from the situation. She just saw that you meant what you said. Now she’s still pitching hissy and lashing out by removing you from a group chat.
How much of that is her problem, and her problem only? All of it.
You did zero wrong. This is exactly how you reinforce a boundary. Textbook.
Either she’ll learn to respect your boundary, or you’ll know she isn’t going to ever respect your needs. Do you want to be with somebody who can’t respect you?
No, I don't. I appreciate the positive feedback from the both of you. I'm sure it's relatable, the feeling that I did something wrong, even though I know I didn't really. Minor correction, though. She removed herself from the group chat. Not that that impacts anything, haha.
Seriously, though, thank you.
