What are some good broken heart quotes?

"The heart was made to be broken" is a famous quote on the subject of heartbreak from novelist Oscar Wilde. Mark Twain once said about love "Never allow someone to be your priority while allowing yourself to be their option."

Nicholas Sparks, romance novelist author, wrote in his book "At First Sight" that "The emotion that can break your heart is sometimes the very one that heals it," speaking on growing from the experiences of a broken heart. Kahlil Gibran once said "Ever has it been that love knows not its own depth until the hour of separation," meaning people don't always comprehend the depths of love until the heart is broken.
