Guys, Is he Feeling what I’m feeling?

My guy friend has been acting very different… he playfully tried to bite me.. he looks at me differently with his eyes makes me feel like he wants something more.. he asks me about my dating life … he checks me out and makes sure we see each other at least once a week to have lunch which he always pays and refuses to have me pay.. I tried. I just would like clarification so I can say something to him. Problem is he tells me of the girls he’s seeing but gets upset when I tell him about a guy. Upset in the sense he will leave lunch and not talk. Is there something there or am I seeing something else?
