Gloria Sings the Blues (S04E22)

Gloria comes home from work one evening in a total apathetic mood. When Archie tries to find out what's wrong with her, she snaps at him and storms off. Later, Edith gets to the bottom of Gloria's mood when she confides in Edith that she thinks that she has temporarily fallen out of love with Mike (something that Edith confesses happened to her and her feelings for Archie).
