I went on a second date today with a girl, first date took us around 5 bars in town and this time we went for a small bite and some minigolf.
during the time in between she already invited me to meet up with her friends, so I figured I would be good tonight.
banter was ok, conversation was good, and she allowed any kino advances I made (hand on the back, hand on the knee, ... )
Untill the last half an hour (was out for 4 hours)...
I felt like she got bored and we ran out of things to say, she was no longer investing.
So in the end I felt like I had massive attraction before the date and it got lower towards the end. It feels like I should have swung for it, but I didnt

The disintrest at the end also made sure a kiss didnt happen.
any tips on how to recover now, when to text/or wait a bit for her? when to schedule a third date and how to proceed there?
