Had a date go pretty well with a girl the other day. I texted her 2 days later, she responded the next, I responded that night, and the window between our texts kept narrowing. Is that normal; it feels obvious we are both waiting(her to almost match my response delay, and then me to like halve my previous one)? What should I be using as a response delay system?

Also, she is way hotter (10) than girls I'm used to dealing with (~8s) so I'm sort of overthinking things a bit, and I can feel myself get nervous in a way that I know I wouldn't with another girl. Any trick to overcome that?

Finally: How long before I should invite her to do something again? The first date was a coffee date that went over an hour and felt great and comfortable and enjoyable both ways. What sort of date would be reasonable for a second, and would it be appropriate to invite her back after it? (I'm used to just inviting 8s over after the coffee date but this girl was so hot I choked).
