So I 23 F was supposed to go on a date with this guy from tinder a few days ago (exploring caves at a national park), but his work called him in so he had to cancel. We continued to text for the rest of the day on and off but now I gotta figure out how to bring up rescheduling without seeming pushy. How the hell do I do that?

I was actually the one to ask him out on the first date for reference
