More than friends?

Hey, I’ve known this guy for years (20+), we dated when we were kids, both met other people, subsequently these relationships have ended (long time ago), pandemic brought us back in touch with each other.

We’ve been hanging out really regularly, he contacted almost every day. However, he was going through a bit of a messy (and silly) break up with a girl he dated for a couple of months, so was totally unavailable emotionally and I wasn’t in that place anyway. We both made it clear we were friends and to be honest I’ve been happy sitting in this place for a few months.

Fast forward, he went away on holiday with family. He made contact sporadically whilst away and called one day just to chat, etc. Day after he gets back we hang out, for the first time he complimented me on looking nice… so I think okay, cute. Then he makes a thing about me reading some text messages from his ex, which he has never done before. Asked me outright if I was dating. Saying he’d like to meet my closest friends. Then let’s me know a girl he added on his social media is just a friend he knew from ages ago and she is getting married next year, even shows me the message by getting me to look at something else and her message happened to be there. But then when we get back to mine, doesn’t want to eat (usually we do quite normally), leaves earlier than normal and the contact has slowed down. He still made future plans though.

So I’m like wait a minute…this is all really strange stuff, to the point I’m noticing it. Have I caught feelings, probably judging by my reaction and that this has been playing on my mind. So I just needed a non-bias opinion as my friends and family think he likes me, but I dont want mess anything up by making wrong assumptions. I’m not sure what to do.
