Heartaches (1981)

A young wife becomes pregnant, but the child's father is not her husband. Afraid to tell him, she leaves home, and meets an outgoing, free-spirited woman on a bus. Although the two are polar opposites, the wife moves in with the young woman, and finds out that they have much more in common than she realized.
