David Levithan said this quote
“ An unarticulated crush is very different from an unrequited one, because at least with an unrequited crush you know what the hell you're doing, even if the other person isn't doing it back. An unarticulated crush is harder to grapple with, because it's a crush that you haven't even admitted to yourself. The romantic forces are all there -- you want to see him, you always notice him, you treat every word from him as if it weighs more than anyone else's. But you don't know why. You don't know that you're doing it. You'd follow him to the end of the earth without ever admitting that your feet were moving. ”
