The Love Mates (1970)

Julien, an antique dealer and Agatha appear to be a great couple, loving, caring and seem to feel complete with each other. Though Julien often gives the impression of being interested in other girls, she doesn't care all that much and sometimes even looks like she's encouraging him to do that. She also agrees that the beautiful dark Madly will stay in their immense house. With pain in her heart, she discovers that he loves her very much, and that she will definitely take care of his happiness.
