Cette citation est attribuée à Honoré de Balzac, extraite de son œuvre 'La Physiologie du mariage' (1829), un essai satirique sur les relations conjugales dans la société française du XIXe siècle.
"Love almost always ceases at the moment when it was about to become reasonable and founded on something. Between novelty and habit, one an invincible attraction, the other a powerful bond, there is an abyss to cross in which love falls and almost always perishes."
