What is the meaning of heartbreak you ask?
It's when you cry yourself to sleep every night.
It's when you wake up on the morning not wanting to get up because you you know the only way you can have him is in your dreams.
It's when seeing him with her makes you all shaky and you feel your heart break a little more.
It's when you know that you can't live without him but he can live without you.
It's when everything you see and hear reminds you of him.
It's when just thinking about him brings tears to your eyes.
It's when you can't eat or sleep
It's when you feel incomplete and lonely all the time
It's when your feelings toward him are not returned.
That's what heartbreak is.
