Slow burn or delusional be ruthless

Okay so at my first ever job I met my coworker and for some reason immediately liked him but nothing more than a chill work crush yk. Eventually I end up like actually liking him and damn near obsessing over him with pretty much no reciprocation because we spent a lot of time tg at work and acc became friends.

Over the course of 3 years working tg we had spent a lot of time hanging out at work school and socially but nothing romantic ever happened like at all. We stayed cordial friends (like our friend groups never mixed at all and we would still talk every once in a while) after we both quit tg on the same day because I had gotten a new job and we was just over it ig idk.

I was young and delusional at the time yes, but this is why I need advice.

Fast forward 5 YEARS I’ve moved away from our home town have a whole new life and I cannot believe it but I STILL like him. I find myself always thinking of this situation as Invisible string theory vibes which makes me think I’m just so far gone in delusional land I’m unsavable, but hear me out. When we first started working tg about 6 months in we discovered we had acc gone to grade school together but he transferred in around year 6, than we find out we live on the same street in our hometown and have since we were born, THAN fast forward to a couple months ago I find a picture of us at like 5/6 years old together in a class picture. I immediately sent him to him just because of how crazy it was to find that 5 years later and we haven’t spoken at all and only Briefly bumbed into each other once in the past year. Anyways idk it literally could mean nothing but coincidences exsist.

OH AND, now current day, he and I snap ,yes ik snapchat ew wtv, everyday and I’ve heard through mutual friends that he talks about me more often than I ever would’ve thought which makes me feel like wait maybe im not crazy and this guy could acc see me in the same confusing kinda way i see him? ANYWAYS, I want to know your opinion on this whole situation like I don’t know why I even could possibly still like him like this after so many years of being nice when we see eachother but living such separate lives, and am I crazy and read wayyyy to much into things?
