why does love hurt?

Truly one would believe if they loved someone and the other person supposedly loved them then it would be picture perfect, true?
Instead love can truly rip you to shreds, leaving your very soul in tatters.
Is that love?  Can love be both earth shattering and heart breaking?
Do they go hand in hand?

Is it possible to survive the heartache, the lies,m the rawness, the loneliness the confusion?
