Being in love is a good thing, but it is not the best thing. It is a noble feeling, but it is still a feeling ... If the old fairy-tale ending "They lived happily ever after" is taken to mean "They felt for the next fifty years exactly as they felt the day they first met," then it says what probably never was nor could ever be true, and would be highly undesirable if it were. Who could bear to live in that excitement for even five years? What would become of your work, your appetite, your sleep? But, of course, ceasing to be "in love" need not mean ceasing to love ... It is a deep unity, maintained by the will and deliberately strengthened by habit; reinforced by the grace which both ask, and recieve, from God."
C.S. Lewis, "The Four Loves"
... I know I have a lot to learn, but I think Lewis has a point.
