How we cite our quotes:
She, his Dolly, forever fussing and worrying over household details, and limited in her ideas, as he considered, was sitting perfectly still with the letter in her hand, looking at him with an expression of horror, despair, and indignation. (1.1.9)
Oblonsky views his wife as constantly engaged in mysterious female occupations; when there is a problem he finds her sitting absolutely still.
Stepan Arkadyevitch was a truthful man in his relations with himself. He was incapable of deceiving himself and persuading himself that he repented of his conduct. He could not at this date repent of the fact that he, a handsome, susceptible man of thirty-four, was not in love with his wife, the mother of five living and two dead children, and only a year younger than himself. All he repented of was that he had not succeeded better in hiding it from his wife. But he felt all the difficulty of his position and was sorry for his wife, his children, and himself. Possibly he might have managed to conceal his sins better from his wife if he had anticipated that the knowledge of them would have had such an effect on her. He had never clearly thought out the subject, but he had vaguely conceived that his wife must long ago have suspected him of being unfaithful to her, and shut her eyes to the fact. He had even supposed that she, a worn-out woman no longer young or good-looking, and in no way remarkable or interesting, merely a good mother, ought from a sense of fairness to take an indulgent view. It had turned out quite the other way. (1.2.1)
Not only is Oblonsky unrepentant regarding his infidelity, but he also thought that Dolly would condone it because he lets her manage the household affairs. The fact that Dolly is no longer attractive to Oblonsky serves another justification for his infidelity. He finds it difficult to believe that a man in his position would not commit adultery.
Darya Alexandrovna meanwhile having pacified the child, and knowing from the sound of the carriage that he had gone off, went back again to her bedroom. It was her solitary refuge from the household cares which crowded upon her directly she went out from it. Even now, in the short time she had been in the nursery, the English governess and Matrona Philimonovna had succeeded in putting several questions to her, which did not admit of delay, and which only she could answer: "What were the children to put on for their walk? Should they have any milk? Should not a new cook be sent for?" (1.4.40)
Dolly carries sole responsibility for the running of the Oblonsky household. Tolstoy consider the home to be a woman's domain, and Dolly is a "good" woman because she attends to her family. Check out Dolly's "Character Analysis" for more on this topic.
