Which sentence in this excerpt from leo tolstoy’s the death of ivan ilyich suggests that ivan ilyich tried his best to escape from the reality of his troubled family life?

praskovya fedorovna blamed her husband for every inconvenience they encountered in their new home. most of the conversations between husband and wife, especially as to the children's education, led to topics which recalled former disputes, and these disputes were apt to flare up again at any moment. there remained only those rare periods of amorousness which still came to them at times but did not last long. these were islets at which they anchored for a while and then again set out upon that ocean of veiled hostility which showed itself in their aloofness from one another. this aloofness might have grieved ivan ilyich had he considered that it ought not to exist, but he now regarded the position as normal, and even made it the goal at which he aimed in family life. his aim was to free himself more and more from those unpleasantness and to give them a semblance of harmlessness and propriety. he attained this by spending less and less time with his family, and when obliged to be at home he tried to safeguard his position by the presence of outsiders. the chief thing however was that he had his official duties. the whole interest of his life now centered in the official world and that interest absorbed him. the consciousness of his power, being able to ruin anybody he wished to ruin, the importance, even the external dignity of his entry into court, or meetings with his subordinates, his success with superiors and inferiors, and above all his masterly handling of cases, of which he was conscious—all this gave him pleasure and filled his life, together with chats with his colleagues, dinners, and bridge. so that on the whole ivan ilyich's life continued to flow as he considered it should do—pleasantly and properly.
