Title.
I understand that most will probably say "You cut them off," "stop being friends with them," "they weren't your friend all along," or the like. Life isn't that black and white, but I can agree that those sentiments aren't necessarily wrong.
EDIT: It's been ~6 months since I've spoken with the person despite them reaching out multiple times. I did not/have not communicated with them the issue, and I'm not sure they even remember or realize they even said what they said.
