Der Klügere zieht aus(2012)

Overview:

Peter and Nina, both around 40 and parents of two children, decide to part as harmoniously as possible. However, Peter only moves to the summerhouse. The firm decision of Peter and Nina: "We want to remain friends and continue to care for our children as well as possible." This is not just lip service but really the intention of both parents. After all, you're grown up. Already at the very beginning of her new life, however, it can be felt that Peter does not take this separation as seriously as Nina, who is clearly the driving force behind Peter's departure.
