Does he possibly like me?

For the past few weeks, I get the feeling a coworker may have a crush on me. I don't want to jump to conclusions but he genuinely has this nervous and shy energy around me when he seems to be fairly confident. Today kinda brought this to my full attention.

Reason is when I caught him staring, he turned his head so fast you would think he broke his neck. Whenever we're walking head on, he goes above and beyond not to look in my direction. Lastly, we don't communicate but we share a mutual coworker between us that we both communicate with. While she was talking to us both, I seen him staring at me from the corner of my eye but again when I'd look he'd look away.

This is all kinda hilarious to me. What's your guys take on this? Nothing wrong with a work husband, doesn't hurt that he's cute.
