Is he interested in me or is this all in my head?

i have a crush on this guy at my work and we make eye contact a whole bunch, especially from a long ways away, and everytime he looks away really quickly. sometimes i will even see him looking at me through my peripheral vision when i walk past him. and this happens basically every shift i have with him. plus he gets clumsy and drops whatever he is holding when i walk past.

we don't talk a whole lot, but when we do it's short and sweet just hi how are yous (i'm also shy). he also acts differently around me compared to other people. like he will be talking with his friends and the moment i walk in he is very quiet and the conversation ends there.

i've also noticed he's copied my phrases and language when i hear him talking to other coworkers, he walks by my work area multiple times when there's a much shorter route to his destination, he sometimes follows me like if i take my break and he sees me he will follow me to the break room and linger a bit and then turn back around.

am i delusional?
