Breakfast in Bed(1963)

Henry and Liane Clausen's marriage is not going well. Henry is an ambitious publisher who is very focused on his career and neglects his wife Liane. In order to shake her husband out of his indifference, Liane Clausen begins an affair with Victor Armstrong. She expects his jealous reaction to confirm that Henry still has feelings for her. But Henry reacts differently than expected: instead of making a scene, he also begins an affair.
