Y does it hurt?

Y does it hurt so bad,
Y do i feel so sad,
I thought i could get ova u,
But i keep crying cause i still luv u,

Isn't luv supposed 2 b spectacular,
Good ova Evil,
So y does it feel as though it will neva b that way.

It hurts when ur scared 2 tel sum1 u luv them,
It hurts when ur in love and u have 2 trust them,
It hurts when u argue,
And it hurts when u break.

So is luv really joy,happiness,pleasure and all the other wonderful feelings in life.

Or is it really supposed 2 cause so much hurt and pain?
