Goodbye Again (1961)

In this adaptation of Françoise Sagan's best selling novel, Paula is a beautiful and highly successful 40-year-old businesswoman. She is deeply in love with Roger, her mature consort of five years. Roger is a very charming gallant who loves Paula but is too selfish to give up his freedom to be promiscuous. When Paula meets Phillip, the 24-year-old immature lawyer son of one of her rich clients, he falls hopelessly in love with the glamorous, sympathetic older woman and insists that the age difference will be no barrier to a romance. Paula resists the young man's persistent advances, but she finally succumbs when Roger initiates yet another affair with one of his young Maisies. An affair begins, and society does not approve.
