Getting ghosted after a date?

Last weekend I went on a date with a guy from Tinder. It wasn't bad, but I also didn't leave thinking I really liked him. I had reached out the next day to thank him again (something I always do) and he responded, yada yada. He was the one who left me on open. Anyway, we stopped talking. I've been on quite a handful of dates and I've never had this happen to me so I feel kinda shitty and I'm wondering what went wrong for this to happen. It wasn't a glaringly bad date, he basically talked about himself the entire time (lol) and we joked around a bit. How do you guys deal with this feeling lol 😰 I'm not upset that HE ghosted me (I barely knew him and wasn't head over heels) but it's more like I'm left wondering now if he thought I was ugly, if I said something weird, etc, but I can't think of anything weird I could've said.
