The following wiki article talks about adding Events in the Family Editor. (Specifically, it discusses leaving the relationship as “Married” even after adding a “Divorce” event.)

When “Adding” the first Event in the Family, Gramps ‘guesses’ the event type will be a Marriage. If a Marriage event exists, the new Event Editor form ‘guesses’ the next type will be a Divorce.
A “Marriage” event must be added to a Family with the “Family” role. It needs a date to be properly inserted in a timeline. And a Place with coordinates to be plotted on a map. It needs both (date and coordinates) to be plotted on a timeline map.
Note: the default new relationship type is “unknown”. Since most relationships being entered are likely to be “Married”, there is an input option in Preferences to change that “default family relationship”. This saves an input action for the majority of the data being entered.
