Why Does love hurt?

There's one thing that everyone would get effected by no matter how old or young...
no matter who they are or where they come from...
it could grab ahold of you and never let go...
and the ones who doesnt care for it as much will and mostly are the ones who'll forever grow...

But how could it be such a demanding thing...
Did God give us this punishment because of Adam and Eve..
It was meant to be lovely and not used to hurt someone..
but its not the others fault for how much of the others sprung...
it can be used to tear your heart apart and create your future...
weather you want it to do it or not it stays mutual...

Why does it hurt so much when most of its meant to be...
what in the hell did i do? why did it have to come f**k wit me...
Why did it have to make its way into my world...
How could it hurt so many people and its only a 4 letter word?!!!
