The Valley of the Moon by Jack London — Read

Saxon had been clear-eyed all her days, though her field of vision had been restricted. Clear-eyed, from her childhood days with the saloonkeeper Cady and Cady's good-natured but unmoral spouse, she had observed, and, later, generalized much upon sex. She knew the post-nuptial problem of retaining a husband's love, as few wives of any class knew it, just as she knew the pre-nuptial problem of selecting a husband, as few girls of the working class knew it.

She had of herself developed an eminently rational philosophy of love. Instinctively, and consciously, too, she had made toward delicacy, and shunned the perils of the habitual and commonplace. Thoroughly aware she was that as she cheapened herself so did she cheapen love. Never, in the weeks of their married life, had Billy found her dowdy, or harshly irritable, or lethargic. And she had deliberately permeated her house with her personal atmosphere of coolness, and freshness, and equableness. Nor had she been ignorant of such assets as surprise and charm. Her imagination had not been asleep, and she had been born with wisdom. In Billy she had won a prize, and she knew it. She appreciated his lover's ardor and was proud. His open-handed liberality, his desire for everything of the best, his own personal cleanliness and care of himself she recognized as far beyond the average. He was never coarse. He met delicacy with delicacy, though it was obvious to her that the initiative in all such matters lay with her and must lie with her always. He was largely unconscious of what he did and why. But she knew in all full clarity of judgment. And he was such a prize among men.
