How do guys act when a guy is falling for a girl but doesn’t want to? does my story relate?

i have a co worker i feel a strong connection too. we have flirted before and he stares at me from a far. but sometimes when i’m around it seems like he avoids me. today i had to wear my scrubs to work for a job after my full time job and it seemed like he was completely avoiding me. yesterday he was very flirty. sometimes i just feel like he’s randomly super distant and other times he’s totally into talking to me and flirting. does this mean he has feelings but is maybe scared to fall for me? what do you think
