The Constant Wife; by W. Somerset Maugham.

He has been having an affair, and she has been trying to keep a good front for sake of the home, the children, the society.

A friend returns from abroad with lvoe for her still in his heart, and his eyes light up when she walks into the room. She takes him up on his offer to go away - and the husband confronts her.

How she smoothly irons those difficulties is the delight and the charm of this work, this writer. She intends to go, have the holiday, and return to her home - and cannot be threatened out of her well deserved vacation or her home either, the husband has lost the moral right and does not have the courage to be exposed to the public eye as the philanderer he has been and they have all known.
