Why does love exist ?

     Maybe LOVE exists only to make us happy and to make us believe that we can fly. It gives us wings and halos. Actually, love can make us to smile for no reason. Am I right ?
     When you're in love, you think differently. You can say things and think about things that you thought you never would. Am I right ?
     There is a person that completes each of us. I mean, God make us like halfs souls. We have to find our soulmate. Am I right ?
     Have you ever been in love ? How did you feel ? Didn't you feel exactly like I said ?
