First date: is this guy interested at all or was he just being polite?

I recently went on a date with a guy I met on Bumble. I’m from a city about an hour away and was staying at a friend’s house in the city he lives in. I took a Lyft to the restaurant and met him there. He asked for my phone number before the date was over (we kept all communication on the app before we met). He opened doors for me, dropped me off at my friend’s house, we made out for about 10 minutes, and then he texted me literally two minutes after he dropped me off to make sure I got inside okay (he watched me go in my friend’s house, so he knew I got in okay). He also texted me the next night to make sure I made it back to my city okay. Before he dropped me off, he did ask me the next time I’d be in his city, but I said I didn’t know (because I don’t). No plans of a second date were made, and I’m guessing that’s because of the hour difference between us. I do like him, though. Does it sound like he’s interested to you guys? Or was he just being polite? Should I text him next time I’m there?

I’m only 24 and I’ve been in a LTR for a few years and I haven’t dated much. I know how rare it is to come back from a first date actually liking someone. The main reason I ask this is because one of my friends told me I made it seem like I wasn’t interested because I told him I didn’t know when I would be back to his city. She said that was essentially him putting the ball in my court – is this true? That really wasn’t the case – I truly don’t know when I’ll be back. Basically, I’m not good at dating haha. Thanks for your input!
