The movie I search is Italian and from around the early eighties and set in the same time. It is possibly a TV-movie, but I am not sure. It is about a young woman around 20 years old who is romantically together with a young man the same age. They are friends with another young man the same age. She becomes drawn to this other boy and they become together. Yet, they continue to be friends all three. However the friendship between the boys takes over so the girl becomes a bit superfluous. In the final scene she lies by the edge of a roof and the spectator does not know if she will roll over it. It is a low key psychological relation drama.
