Why does he ignore me when he sees me?

Anonymous
I matched with this guy on tinder a month ago and we talk every day. he works in my college and is only a few years older than me. Anytime i see him he puts his head down and acts like he never even saw me! Like, today i was in the canteen getting a drink and he was waiting right behind the cashier on his food and as soon as he saw me he looked down at his phone and whilst i was paying i could see him looking at me out of the corner of my eye.
why does he do this?
