Søren Kierkegaard said this quote

Love is everything. So, for one who loves, everything has ceased to have meaning in itself and only means something through the interpretation love gives it. Thus if another betrothed became convinced there was some other girl he cared for, he would presumably stand there like a criminal and his fiancée be outraged. You, however, I know would see a tribute in such a confession; for me to be able to love another you know is an impossibility; it is my love for you casting its reflections over the whole of life. So when I care about someone else, it is not to convince myself that I do not love her but only you—that would be presumptuous; but since my whole soul is filled with you, life takes on another meaning for me: it becomes a myth about you.—Johannes the Seducer, from_Either/Or_
