He knows I liked him in the past - what’s he thinking now?

I built a connection with a guy over the course of a few months. During this time he’d ask me personal questions, extend convos when he didn’t have to, said my name often, said things like “nice to see you as always”, would open up about his personal life/family, and made sexual jokes about me. It seemed like he was flirting, so eventually I tried to open the door (not directly, but I made my interest known)

We had a bit of a deeper convo one time that went longer than it needed and he opened up, and then he pulled back noticeably the next time I saw him but was still kind. He ended up randomly revealing he had a gf, which was interesting bc we talked about everything, and he never mentioned a gf until that moment. So I know he picked up on my interest

Anyway, after that I didn’t see him for awhile. But now since I’ve seen him again, he’s trying to chat and is friendly. He remembers little things I say, and always extends things.

If a guy knew I liked him in the past, how would he typically act if he was into me now?Bc it seems like he’s trying to flirt again. I know he’s single now. The context has where I see him has been a barrier in wanting to be direct at all
