I like bug’s style if there were some good vibes.If you are looking for a “girlfriend” there is nothing wrong with going slower than that either, including if there was some good chemsitry and the date was fun and friendly.

You didn’t blow it. You have to put those little things out of your mind as fast as you can, Don’t dwell on it.
Laugh about it a little.
Humbly assume that there are lots of women who want to meet you, if you don’t do this already. Maybe she still wants to go out with you maybe she doesn’t.

Of course things were not always easy like this for yours truly but I think that is the way to think about it.
