Is this what a slow burn feels like?

I have been on three dates with this man I met off the apps. We're both early 30s. On paper, we have a lot in common. Same creative profession, same politics and religion. He has a good relationship with his family. So far he has been kind, consistent, understanding. Our conversations are nice. He clearly likes me. But When I am with him, it feels more like hanging out with a friend than a romantic interest. Granted, our dates have had to be a bit spaced out because of travel and life stuff, but I don't find myself thinking about him between dates. I don't dread our dates our anything but I'm also not excited for them. We don't text between dates. He's not unattractive, perfectly nice face, but I just feel pretty neutral.

On our second date, he invited me over at the end before we had even kissed and I declined, which he was respectful of, but I felt a bit offput, even though in the past I've comfortably slept with people on date 2. I did try kissing him to see if there was anything there. And it wasn't a bad make out, technically speaking, but it felt sort of... weird and wrong? Like I shouldn't be kissing him?

On our third date, our conversation was good, but I just felt like I was with a friend, did not want to touch him or kiss him and I don't know why. I just felt this mounting pressure in me, like I shouldn't be on a date with him, like I should end it, like it still felt more like being with a platonic friend than a growing love interest. I'm not looking for an all consuming spark, I've gone with that in the past and it hasn't worked, but I'm wondering if I'm feeling enough for a slow burn, or maybe this guy is just too similar to me/not right for me? Or if there is something else going on here. Would love to hear from people who have experienced the slow burn
