If your television show has been running for, say, twenty or thirty years, and you have finally, in a moment of weakness, allowed your romantic leads to marry, you can always create romantic tension all over again by separating the couple. The separation is most easily accomplished by having the female half of the pair declare that she “needs space.” This is inherently plausible, because everyone knows that a female television character periodically “needs space” even though she lives in a Manhattan apartment the size of a cathedral. With careful management, you can build a season-long story arc on the foundation of the woman’s need for “space.” Then, for next season, there’s always amnesia.
