It's not when you fall in love,
It's when you fall for someone who has no love for you. 
It's not when it bleeds,
It's when you see how much you bled.
It's not when it hurts,
It's when you realise how much it hurt.
It's not about losing hope,
It's about how long you went without hope.
It's not about accepting defeat,
It's about how there was no chance to even succeed.
It's not about being broken,
It's about not realising how broken you were.
It's not about losing love,
It's about losing the person you love.

That's pain.
