A sad story in 3 sentences here. This guy probably thought he was being sweet in letting the girl know that she was mistaken, and she wasn’t unloveable. Her response, though, does kind of give the game away that she may not be unlovable, but she is pretty shallow.
I would suggest that he had a lucky escape, even if it did come with a hefty side of insult. Maybe she is destined to be alone if she’s going to be that picky, and that cruel. Her second tweet is a bit of a self-own and doesn’t paint her in a great light either, wonder if she’s still single.
