C.S. Lewis
"But, of course, ceasing to be 'in love' need not mean ceasing to love. Love in this second sense -- love as distinct from 'being in love' -- is not merely a feeling. It is a deep unity, maintained by the will and deliberately strengthened by habit ... 'Being in love' first moved them to promise fidelity: this quieter love enables them to keep the promise. It is on this love that the engine of marriage is run: being in love was the explosion that started it."
