Woman in a Dressing Gown (1957)
Amy and Jim Preston have been married for twenty years but, in her husband's eyes, she has become sloppy both about the house and herself. Jim has no problems with falling in love with Georgie Harlow, a fellow-office worker who is pretty and young...and willing. Jim finally asks Amy for a divorce so he can marry Georgie, and Amy pleads for him to stay but he walks out. He soon realizes that he can't go through with the desertion of Amy and their teen-age son, Brian, and returns home.
