No, pain is not beautiful. But can one not see the beauty in loving someone so much that it hurts your heart physically and emotionally?
Isn't love that makes your whole body numb beautiful?
I don't really know if this is a poem, but I know sometimes I love you so much that when I'm crying over you and how you'll never love me, I can't help but see so much beauty in the darkness. What better way to hurt than to hurt by loving someone to the point that it shatters your ribs?
