Great first date to slow texting

I (24 F) went on a first date with a guy (25M) last Thursday and it went really well. Before the date, we were texting at a pretty normal frequency. During the date, things went great we have a lot in common and chatted away. he talked about a second date ideas, complimented me a lot, and kisses me goodbye and made it clear he wants to see me again.

He mentioned he’s not really into social media, so maybe he doesn’t normally use his phone much. Since the date, he did mention a date idea but no plan and his responses have slowed upwards of two days or so to reply. We haven’t planned a second date yet.

He’s been hiking on Saturday and Monday, and the mountains he went to are several hours away from the town we live in. I haven’t heard from him since Sunday night.

Am I overthinking this? I know I tend to get anxious, but I can’t help wondering if he’s losing interest or if I did something wrong. I have been trying to keep busy but it’s crossing my mind.
