Ferzan Ozpetek - Le fate ignoranti AKA His Secret Life (2001)

Quote:
When Antonia’s husband Massimo is killed in a car accident, she accidentally discovers that he has been having a same-sex affair with a produce wholesaler named Michele. Although she’s initially devastated by the news and hostile toward Michele, she soon develops a friendship with him and his and Massimo’s circle of gay, transgender, and straight friends, among whom are a Turkish immigrant, a playwright and a boutique owner. As she gets to know these people and become a part of their lives, the new relationships dramatically transform Antonia.
