What should I do?

I went on a first date with a guy and it went really well. He asked what I like to do, and suggested places I could check out since I’m new to the city.

After the date, he said something like “I’ll take you on a proper date sometime,” and also mentioned he’d see me after my trip (for context I’m travelling this week).

We texted a bit after, but the last message was him saying “let me know how it goes if you try one of those places,” (from his suggested list) and I just liked it.

It’s now been about 3 days and he hasn’t reached out again. I’m not sure what to do, I’d actually like to see him again, but idk if he’s not interested or just taking it slow.

Should I just leave it, or reach out after my trip?
