There’s Always Tomorrow (1955)

Fred MacMurray is a married toymaker whose family, despite his best efforts has little need for him. When he feels sparks with a former co-worker who has suddenly reappeared in his life, he is hard-pressed to not see where they land. It’s a typical Sirk melodrama, interestingly told from the male perspective. The co-worker is played smartly by Barbara Stanwyck and the chemistry between the two leads makes you want to root for them despite what it might do to his undeserving family.
