Can my friends with benefits feel more about me?

So there’s a guy we’ve had sex with a couple of times (I’ve known him for years). He says he doesn't feel anything for me. However, I noticed when we are together he can’t take his hand off me, he keeps touching a lot, compliments me, holds my hand while walking. He often asks about my ex-boyfriend or other guys. He asks why I feel this great sexual attraction to him. Sometimes it feels like he's testing the waters. He talks to me about marriage/his future wife or just generally even about his future and what he wants to do.
I don’t feel the need to talk about things like that, but he always brings it up and he wants to know more about me.
Last time I was in his city and he wanted to meet me and show me a nice place, but I didn’t have time for that.
Part of the story is that I currently live abroad for 1 year and he also works in another country.
