Is my crush stalking me on Instagram?

We don't follow each other on instagram because he for some reason won't follow. We follow all of each other friends tho. Once I received a request from him and i accepted it but then he unfollowed me. Does that mean he had to have looked me up and then click it by accident? Another time in school he would quote my bio message from Instagram 3 times with a different bio each time cuz i would change it. We don't follow each other so does that mean he was looking me up?
