I believe it was Shakespeare, or possibly Howard Cosell, who first observed that marriage is very much like a birthday candle, in that 'the flames of passion burn brightest when the wick of intimacy is first ignited by the disposable butane lighter of physical attraction, but sooner or later the heat of familiarity causes the wax of boredom to drip all over the vanilla frosting of novelty and the shredded coconut of romance.' I could not have phrased it better myself.
