How do I know I'm in love?

I don't think that's really love..but more of a big crush. Talk to him more than you do. Get to know him and his basics. Like..his favorite color, movie, band, or food. Something of the sort. Once you know him see if you still feel the same way. It could be love, but you can't really tell..you just know. And trust me, those "symptoms" that may occur will be very, VERY obvious to you.
