Shoot the Moon (1982) DVD

Follows the crumbling marriage of successful writer George Dunlap and housewife Faith Dunlap, who live with their four teen to adolescent aged daughters in a farmhouse they renovated in Marin County. This phase of their story begins in George moving out of the house not only in the problems that he and Faith have been having, but acknowledgment that George has been having an affair. But their future is not as easy as love having left their marriage in their problems, and thus they moving on from being husband and wife, as there is a certain emotional comfort in their relationship. While George would rather be with his girlfriend Sandy, he also wants to retain his role as lord and master of the house and family, including of Faith. And without George, Faith may want to move on to at least testing the waters with other men, perhaps for company, perhaps for sex, and/or perhaps to spite George. It doesn't help for George that the first man she chooses as somewhat of a serious boyfriend is Frank Henderson, the contractor she unilaterally hires to build a tennis court that George doesn't want on the property. Then there is the issue of the children, the breakup outwardly affecting the oldest, Sherry, the most in she somewhat understanding what is happening, but still not helping but be mad at turns with her father and then her mother about their new family situation.
