It is not an idiom. Unkindness is often called heartlessness, and so the expression "have a heart" means "Do not be unkind."
People believed that the feelings came from the heart and when you had negative feelings that it was your heart slowly falling apart and that when love failed you lost not only the thing that caused the feelings but also a piece of your heart.
Unless there is truly something wrong with your heart, then yes, it is an idiom. My heart fell, my heart exploded, my heart sang, my heart doing anything other than pumping blood is an analogy and an idiom.
