Most Helpful Guy
It depends on how he's doing it. If it just the odd glance here and there it probably doesn't mean anything. Can you really say you've never looked at a guy every now and then? On the other hand if it obvious and happens all the time, that's not good and probably means he's either not interested in you anymore or doesn't respect you. He sounds like an asshole anyway. When a guy goes out with a girl, his focus should be on her.
