i agree, and i've experienced both in a "just friends" setting. (intimate setting definition may vary from person to person)
i must also include culture/the way a person is raised comes into play. a lot of guys are raised to pay for the meal because it's the gentleman thing to do. maybe? yes?
anywho, i know the op has other factors into play.
OP, i say don't miss out on a good friendship
if he is not interested in more.
