There could be several reasons why your crush keeps looking at you. Here are a few possibilities:
Interest: If they are interested in you, they might find themselves looking at you more often. This could be because they're attracted to you or they're curious to know more about you.
Familiarity: Sometimes, people look at others simply because they are familiar to them, especially in a room full of strangers or acquaintances.
Coincidence: It might be that you've noticed them looking at you a few times, and now it feels like they're always looking because you're paying more attention.
Body Language Reading: They might be trying to read your body language to understand how you feel about them or to gauge your reactions to certain situations.
They Know About Your Feelings: If they're aware that you have a crush on them, they might be observing you more closely to understand their own feelings or to decide how to react.
It's important to remember that these are only possibilities, and it's often hard to know for sure why someone behaves the way they do. The most reliable way to understand why your crush keeps looking at you is to communicate with them directly. This might be a bit uncomfortable or scary, but it's often the best way to clear up any misunderstandings or uncertainties.
