Come Back, Little Sheba (1952)

For two decades Doc and Lola Delaney avoided coming to terms with what Doc considered a "shot gun" marriage. Lola lost the baby and gives a lot of her affection to Sheba, a dog that disappeared a few months before the film opens. Doc blames Lola for having to drop out of medical school and not becoming a "real" doctor. Until joining AA a year ago, his escape was alcohol. Then college student Marie rents a room in their home. Doc feels passion for the first time in 20 years. But Marie has two suitors her age. Lola -- unaware of Doc's emotions --becomes as interested in Marie's future as if Marie were her daughter.
