Ich heirate meine Frau (2007)

After more than 25 years of happy marriage, Henriette and Werner Wallner have been living apart since a relationship crisis. While Henriette copes well with the separation and flourishes as the self-appointed "manager" of her daughter Elke's flourishing cake store, Werner, who is plagued by heartbreak, does everything he can to win his wife back. However, this is easier said than done, as the handsome and wealthy Saudi Abdul Al Hakim is also courting Henriette by every trick in the book. With this competition, Werner has to work hard to impress "his" Henriette.
