I believe much of the pain of a breakup comes from having a life plan that you have fallen in love with. When it does not work out, you become angry that you now have to pursue a new life plan.

Karen Salmansohn

You like someone who can't like you back because unrequited love can be survived in a way that once-requited love cannot.

John Green

God is closest to those with broken hearts.

Jewish saying

Broken heart will turn into a stronger one within hope.

Toba Beta

The bitterest tears shed over graves are for words left unsaid and deeds left undone.

Harriet Beecher Stowe

Come live in my heart and pay no rent.

Samuel Lover
