So, my coffee date yesterday went pretty well. She was very easy to talk to and had a nice relaxed personality. She was dressed a bit nicer than me though

Hope she didn’t think I looked too sloppy. Anyway we went to a coffee shop in town and talked for a bit over an hour. I felt like there was some nice romantic energy going on.
Then she suggested we walk home together (we live pretty close-by each other). All in all the date took about two hours, but it felt like the tension died down a bit on the walk back. I didn't try to go for a kiss when we said our goodbyes but gave her a hug instead. Might have been a mistake, not sure, but I didn’t feel the vibe for a kiss. Anyway, she said she was interested in meeting up again. I sent her a text an hour after getting home saying I enjoyed the date, and she replied quickly saying she did too and that we should meet up soon, so that must be good right?
I hate playing games, but decided against contacting her today. Will probably hit her up tomorrow or on Sunday and suggest another night next week. We set up our first date by text and I prefer doing it that way, but I stupidly said something about calling. Should I follow up on that or can I send her a text instead?
Oh, and do you have any good suggestions for what to do on the second date? I think she is expecting coffee again, because I jokingly told her that she would pay next time when buying the coffee (gender equality is a pretty big thing here, so it may have come off as creepy/old-fashioned if I had just paid for everything without such a comment, plus it was a good way to sneakily set up another date if she is interested) but I think I want to do something more active/fun. I’m afraid we would be running out of getting-to-know-each-other topics if we just did another coffee. But since she may feel that she should be paying I don’t want to come up with anything more expensive. Do you have any suggestions? Maybe another coffee would still work out.
Man, I suck at and overthink this stuff, lol.
Anyway, most important: The date felt good. I think I like this girl
