what was the "last straw" that made you cut off a person you once considered a good friend?

My former best friend. Her attempting to invalidate my feelings for the 3rd time, unapologetically. I brought up to her, politely, that I've been feeling neglected for a while. That I shouldn't always have to be the one to ask to hang out. She got very angry, accused me of doing the things that I politely brought up to her as my own concerns (in short, gaslighted me, straight up lied even about a bunch of things). I gave her a day this last time to re-evaluate what she said, to re-think things. I had hoped since she was drunk when we argued, that she would.

Instead, she doubled down on everything. She showed complete disinterest and apathy in me saying that I was about to leave for good. That was the worst of it all, and when I knew it was doomed. Still tried to apologize later, because even if I know my feelings are my feelings and I was hurt and had been hurting for a while, I still cared about our friendship, and only got immediate hostility again. Her final response was essentially "I'm sorry you feel that way, I don't care if you leave". So I left, and while I've grieved, I haven't looked back.
