When one is in love, one always begins by deceiving one’s self, and one always ends by deceiving others. That is what the world calls a romance.
– Oscar Wilde
The Picture of Dorian Gray, Chapter 4. Lord Henry. Before Lord Henry says this, he asks Dorian what his actual relations are with Sibyl and Dorian snaps at him that Sibyl Vane is sacred. It takes the cynical Henry to turn Dorian’s idealistic talk about love to a conversation about sex deception.
