Daddy(1991)

Oliver Watson has never been luckier: he is a successful advertising executive, shares a marriage of eighteen years with Sarah and has three loving kids: 17-year-old Ben, 15-year-old Melissa, and 9-year-old Sam. His perfect life suddenly falls apart when his wife Sarah announces that she wants to enter a graduate school 200 miles away from home, as she regrets that she gave up her bohemian protester's life and promising writing career to become the wife of a conservative traditionalist. Oliver unsuccessfully tries to save his marriage, until Sarah announces that she is seeing someone else. The children start acting out as a reaction and life is complicated by the death of Oliver’s mother and accepts a job in L.A. where he falls in love with Charlotte Sampson. Life again challenges Oliver when Charlotte is offered her dream job on Broadway.
