I am Love
(2009)

Super melodramatic but very swoon-worthy movie.

Edo finds out about his mother Emma’s (Tilda Swinton) affair with his friend Antonio at a dinner. He leaves the table, and when he and Emma argue he trips and hits his head, dying later that night.

After the funeral, Emma tells her husband she loves Antonio.

Back at the villa, Emma packs and leaves. Downstairs, the family sits speechless and finally Eva, Edo's girlfriend, reveals that she is pregnant.

Thanks Jon S!
