Wife Tames Wolf (1947)

Caught philandering (for the 1867th time, give or take a couple), Leon's wife (Dorothy Granger) announces (for the 1867th time, give or take a couple as she wasn't always his wife) that she is going to divorce him. His business partner hatches a scheme to cure Leon of his flirting with very pretty girl (and a few ugly ones) he meets, but the scheme has Leon faking a suicide.
