Lucretia, Volume V by Edward Bulwer-lytton

The progress of affection between natures like those of Percival and Helen, favoured by free and constant intercourse, was naturally rapid. It was scarcely five weeks from the day he had first seen Helen, and he already regarded her as his plighted bride. During the earlier days of his courtship, Percival, enamoured and absorbed for the first time in his life, did not hasten to make his mother the confidante of his happiness. He had written but twice; and though he said briefly, in the second letter, that he had discovered two relations, both interesting and one charming, he had deferred naming them or entering into detail.

This not alone from that indescribable coyness which all have experienced in addressing even those with whom they are most intimate, in the early, half-unrevealed, and mystic emotions of first love, but because Lady Diary's letters had been so full of her sister's declining health, of her own anxieties and fears, that he had shrunk from giving her a new subject of anxiety; and a confidence full of hope and joy seemed to him unfeeling and unseasonable. He knew how necessarily uneasy and restless an avowal that his heart was seriously engaged to one she had never seen, would make that tender mother, and that his confession would rather add to her cares than produce sympathy with his transports.
