Guy's Behavior

Guys, why would you take a deep breath after seeing a girl you like?

He's like really unsure of me liking him, and he looked really sad when he saw me today, anyway he avoided eye contact with me and then I turned around and saw when he walked a little futher he took a deep breath. Does this mean he really likes me?
