I met a girl on a blind date, and both of them felt very good, but they sent a text message and didn't reply. What happened?

There are two possibilities. One is that she is interested in you, but for some reason, she has to keep a girl's reserve. You know, there is a saying called "playing hard to get". If so, please go after her and continue to influence her.

The other is that she may not be very interested in you. If so, I suggest you divert your attention. None of the people on the blind date field are real goddesses.
