Making Love (1982)

A successful young Los Angeles doctor and his equally successful television producer wife find their happily-ever-after life torn asunder when the husband suddenly confronts his long-repressed attraction for other men. Zach and Claire live a comfortable life, secure in their love for one another when Bart, a swinging Los Angeles novelist, walks into Zach's office for a medical check-up and awakens unfamiliar feelings in him. In a move which leaves him feeling wracked with guilt, Zach cancels dinner with Claire in order to go out on a dinner date with Bart. He is inexplicably drawn to this man, who seems intent on keeping him at arm's length. Why can Bart not allow their relationship to grow? he wonders. Exasperated, he asks Bart, "Do you snore? Does anybody ever get a chance to find out?" As Zach's absences become more and more frequent, Claire's concern manifests itself in the suspicion that he is having an affair with another woman. Finally jilted by Bart and feeling alone for the first time in his married life, Zach resolves to tell Claire the truth about himself. Predictably, Claire is shocked that she could have known so little about the man that she has loved for so many years and accuses him of deceiving her from the very start.
