Got ghosted and am really insecure about my judgement now

I (29m) met a girl, we went on (only) two great dates. We had fun, laughed a lot and we made some flirty jokes and texted quite a bit. At the end of the second date we kissed for the first time and agreed after to make plans for a third date. I texted her about an hour later to tell her I enjoyed our date, and to ask her if she got home safely.

No reply for 4 days now. I have not texted her and I actually deleted her number and the chat to make sure I wouldn't.

I have never been ghosted before (went on quite a few dates) and I am struggling with it. Not that it didn't work out, that is whatever it is... I am struggling with the fact I misjudged someone. I feel so insecure and I also feel this will impact my dating experience in the future.

How did you deal with the insecurity about misjudging people?
