Dollars and the Woman (1920)

When self-centered inventor Dan Hillyer needs money to market his invention out West, his pregnant wife Madge withdraws their meager savings from the bank. Robbed on her way home, she runs in desperation to former suitor Arthur Carewe. Carewe loans Madge money, and Dan sets out on his journey unaware that Carewe's funds are paying his expenses. Soon after Dan's departure, Madge becomes dangerously ill and requires hospitalization. Carewe again rescues Madge, becoming her secret benefactor, and she recovers and has her baby. When Dan returns after successfully selling his invention, he discovers Carewe's generosity and becomes suspicious and angry. Carewe finally intervenes and forces Dan to realize the extent of Madge's self-sacrifice, and the family is happily reunited.
