I Wonder How Many People Have Had a Crush On Me

I ran into an old classmate from high-school yesterday that I used to be friends with. I wouldn't say great friends but we hung out from time to time and then lost contact after we both graduated. I bring this up only because she confessed that she used to have such a crush on me back in the day. I had no idea and sat in disbelief as she told me this. So how many people have had crushes on me that I never noticed 😱.
