title: Splitting Up Together
text: The series chronicles what happens when a couple 's marriage is suddenly reignited by their divorce . The couple has three kids who live in the house with one parent on alternating weeks while the other parent lives as a single person who stays in the garage apartment in back of the house . The garage - dwelling , `` single '' partner is free to date while having no responsibilities in the house or for the children . The `` parent '' partner is free to preside over the house and family as he or she deems best . Each week the parents learn a little bit more about what it is they are lacking in the parenting and `` romantic '' parts of their lives and in doing so become better parents ( during their parenting week ) and better romantic partners ( during their single week ) . Often the insight they gain allows them to see why their spouse felt unhappy in the marriage thus helping them to improve as a person . This increasingly improved person they become also becomes slightly more alluring to their ex-spouse making their complete separation seem less likely .
