The Old Maid by Edith Wharton

Delia's fire had been kept up, and her dressing-gown was warming on an arm-chair near the hearth. But she neither undressed nor yet seated herself. Her conversation with Charlotte had filled her with a deep unrest.

For a few moments she stood in the middle of the floor, looking slowly about her. Nothing had ever been changed in the room which, even as a bride, she had planned to modernize. All her dreams of renovation had faded long ago. Some deep central indifference had gradually made her regard herself as a third person, living the life meant for another woman, a woman totally unrelated to the vivid Delia Lovell who had entered that house so full of plans and visions. The fault, she knew, was not her husband's. With a little managing and a little wheedling she would have gained every point as easily as she had gained the capital one of taking the foundling baby under her wing. The difficulty was that, after that victory, nothing else seemed worth trying for. The first sight of little Tina had somehow decentralized Delia Ralston's whole life, making her indifferent to everything else, except indeed the welfare of her own husband and children. Ahead of her she saw only a future full of duties, and these she had gaily and faithfully accomplished. But her own life was over: she felt as detached as a cloistered nun.
