Most Helpful Guy
I am a Southern gentleman and I could not imagine going on a date and having a lady pay for anything. Also, because of my age and position in life, I tend to take ladies to nice restaurants, nice concerts, etc. So all of that happens regardless of how I feel about the particular lady. So, in your case, that behavior may be a reflection on his personality and style and not a comment at all on whatever feelings he may have towards you. This is more likely also because of his age (which I assume is near your age) so I assume he is a mature man and not a boy.

It means exactly what he said. He doesn't want to be exclusive yet and he's probably dating other chicks as well.
