definition please?

have you ever wondered why most of us have to go through so many disappointments for finally find the person that'a made for us? they say its so we can learn from our experiences. but who are they? what do they know? why can't it just be that you know all along who you're supposed to be with? why do you have to be so miserable at times? why is there such thing as unrequited love, and why can it be so real that it has the tendency to cut you deeper than anything else? why don't we just know? why do we love at all? why why why. i wish that there would be no waste of time; that everyone knew who they were meant to be with since they were born. there'd be no heartbreak, no cheating, and everyone would just be happy.

how is it that love can cause so many problems, but at the same time is the only thing that is real enough and true enough to carry through anything? what the hell is this !)(*&(*&^%#$%^&!* we call love? it is more than a thing, more than a feeling, more than an emotion. does anyone understand it?
