It might not be love, though, I'm just saying. It could be a hard crush, or your hormones talking. Chat with him a bit, yeah?
But if you two don't click, then you know what? You're young. You have so much time ahead of you. Even if you do love him, there is time to move on, time to fall in love again. And you know, it is best not to linger, because the longer you hold on, the worse the pain is when you finally feel it.
