In Search of Lost Time [volumes 1 to 7]

by Marcel Proust

If, on the contrary, she dispels with a tactful word, with loving caresses, the suspicions that have been torturing him for all his show of indifference, no doubt the lover does not feel that despairing increase of love to which jealousy drives him, but ceasing in an instant to suffer, happy, affectionate, relieved from strain as one is after a storm when the rain has ceased and one barely hears still splash at long intervals from the tall horse-chestnut trees the clinging drops which already the reappearing sun has dyed with colour, he does not know how to express his gratitude to her who has cured him.

So in this case it's ok to lie.
