A little of mine

Today in my English class, our teacher gave us the topic "LOVE". Everyone discussed very ebullient about the topic. So am I. But today, I listened much more than spoke. I was just busy thinking about all things they said and then, about me. So, a big question was grew in my mind "Am I really in love?". I didn't know. And now I can't find the answer either.
I realized that I didnt know anything about the guy I "think" I fell in love. Am I already love him? Or it's just a strange feeling when there's a guy "think" he loved me, take cared to me, did many things for me?
We have problem now. We make ourself so tired.
Is it real, that we both need more time to think, more distance to know exactly what we feel?
Is it real.......?
