I am super embarrassed to ask this because it might be dumb but here I go?

Okayy so i followed my crush on Instagram like 3-4 days ago and he STILL didn't follow me back.. I don't know what holds him back because he follows EVERYONE from my school except me!!! And i have noticed he gives me some mixed signals and I don't know maybe he MIGHT be a bit interested in meπŸ˜‚ So the thing is that yesterday I posted a story and he watched every single ONE of them and that's all he didn't follow me though πŸ™ƒ What could be the reason and why would he stare and watch my stories if he doesn't like me like at all?( He never said he doesn't like me i just assume)
