Guys, what does it mean when you're always the first one to look away during eye contact with a girl?

Me and my crush often have prolonged eye contact and he's usually the first one to look away. I feel kind of bad why he does it the moment seems so good.

He also mostly stares at me from afar and when he thinks I'm not looking and quickly looks away if I catch him.
