Am I being delusional?

There’s this guy I have a crush on at work and he caught me staring at him a month back and we made eye contact for somewhere between 3-5 seconds since then I notice that he random walks through my area even though there was no reason for him to come that way. Sometimes he says “how’s it going” (sometimes he sounds really shy then the next he sounds really confident) I thought maybe he might have at least noticed me after he caught me staring and started staring back but recently he’s started walking past my area just to ignore my existence I’m starting to think maybe it’s a coincidence that I’ve seen him around more often and I’m being delusional. Could it be a coincidence that’s he’s popping up more often?
