I think it's pretty standard protocol for most women to say the date went well and they would like to meet up again when still face-to-face with the guy they're on the date with.
Minimise the risk of becoming a statistic, and all that.
For messaging with dates, I generally say 2 texts then let them respond (and that's not messages like "hey" "u up?" "Are you there??" But like actual content that they can engage with).
If they don't get back to you, don't take it personally. Just forget and move on.
Yeah tbh you see that kind of thing with non-romantic conversations all the time as well. How many times has someone said "we should hang out more" and you say "yeah, totally!" even though you know you never will, lol.
Definitely a good idea to follow up after the date just to keep the lines of communication open. I don't buy into the whole "wait x amount of time" thing.
