I can't remember the name of this movie!

Hey, about nine or ten years ago I watched the beginning of a movie that was about a guy who was making a living showcasing others' artwork in his gallery, and his wife was a psychiatrist. One of her patients tried to kill herself. Learning that this patient was an artist too, she suggested her husband's gallery. Her husband goes, sees her work, and the next day, when the psychiatrist asks the girl how it went she claims to have made love to the man who came to visit...Her Husband!...Now, I don't remember any of the actors or the name of the movie, so any help would be nice. I watched it on a movie channel (I don't remember that either), so It could have been either new or old then. Any suggested ideas about the name of this movie?
