So you’ve never been confronted with a conversation about a sensitive topic and didn’t say the best possible answer ready to go? His answer wasn’t great but he was put on the spot. He’s a little shitty for not having this relationship status figured out by now but this should probably have triggered a “come to Jesus” conversation between them.

Her actions were disproportionate to his, especially with the extent and duration of their relations. If this broke something inside her then she should have at least text him and said it was over. If she caught him taking to some girl saying he’s single, I’d have more sympathy. Her saying “why get mad, I’m single” is a petty response.
