Beyond by John Galsworthy

The human creature has wonderful power of putting up with things. Gyp never really believed that Daphne Wing was of the past. Her sceptical instinct told her that what Fiorsen might honestly mean to do was very different from what he would do under stress of opportunity carefully put within his reach.

Since her return, Rosek had begun to come again, very careful not to repeat his mistake, but not deceiving her at all. Though his self-control was as great as Fiorsen's was small, she felt he had not given up his pursuit of her, and would take very good care that Daphne Wing was afforded every chance of being with her husband. But pride never let her allude to the girl. Besides, what good to speak of her? They would both lie-Rosek, because he obviously saw the mistaken line of his first attack; Fiorsen, because his temperament did not permit him to suffer by speaking the truth.
