Staring when talking?

i hanged out for the first time with this guy I've been talking with very recently. It wasn't a date because weve just met but it wasn't friendly platonic stuff either; I do feel like we are flirting and there's tension.

Whenever I talked he stared really deeply, softly smiling. He looked like he was really taking in everything i said. he didn't do this throughout the WHOLE afternoon, but did it a lot and I could tell apart the difference. I usually avoid eye contact, but when I noticed i tried to look at him as well whenever he talked. My normal guy friends dont do this. Sure, they smile and look at me but its completely different! Is he interested in me?
