Can I trust my instinct?

So yesterday, there was a function in my apartment. There were a lot of people there, dancing. There was this one guy in green shirt. I lowkey know him since I was in 4th but developed a little attraction or whatever a little over 3 years ago. He's 4 years older than me. I never felt him looking at me, but yesterday, I don't know what is was, a guy feeling or Instinct i felt him looking at me, and turning back to look at me. My friends told me he was not but I don't know my gut feeling told me he was looking at me. I'm nost sure if I was being delusional or anything but, when I got home, my friends encouraged me to follow him on ig. I've been stalking his insta since 3 years but never followed him. So after I followed him, within 5-7 mins he followed me back, which made me think that what I was thinking was actually true. Should I trust my instinct and go for it?
