Christine of the Hungry Heart (1924)

Craving more love and attention than her alcoholic husband, Stuart Knight, gives her, Christine divorces him to marry Dr. Alan Monteagle. They are happy for a time; they have a son, Jeffy; but eventually Alan neglects his wife for his work; and Christine finds the companionship she seeks with author Ivan Vianney. Christine and Jeffy leave Alan for Ivan, but the doctor regains custody of his son, and Christine decides to take care of Stuart, whom she encounters by chance and who is now in a desperate condition. Just before Stuart dies, Alan and Jeffy find Christine and persuade her to come home with them.
