You Belong to Me (1934)

When vaudeville performer Florette Faxon is left penniless with her six-year-old son Jimmy, she relies on the friendship of fellow performer Bud Hannigan to help her get a job. Bud is reluctant to become her partner, as he has proven to himself to be unreliable in relationships, but he tells her to call him whenever she needs help. While working in a beer garden, Florette meets Hap Stanley, an avaricious performer who marries her to get the rights to perform her show routine. Hap dislikes Jimmy and eventually convinces Florette to send him away to school. Both Jimmy and Florette are broken-up over being apart, but Jimmy pretends it is what he wants so Florette can be happy with Hap.
