It sucks, I'm in the same position today after being on a date yesterday. I don't mind the ghosting itself, I'm just wondering what I'm doing wrong so I can change my behavior if I'm doing anything that's no good. During the date I get told that I'm so amazing and she's having such a good time and she definitely wants to see me again and then it's crickets

Can't really do much but to shrug and move on when you've only met each other for such a short period of time, there's somebody out there for everybody.
