I forgot he was divorced before the prequels!
As one version of the story goes, the divorce in '83 (during post-production of RotJ) is a major factor in no additional movies being made for so long. It was a bitter divorce, and should a new movie enter production in short order, Marcia would have been entitled to a cut as part of the community property.
Spielberg also had a bitter divorce at the time. The result: Indiana Jones and the Temple of Doom (with people having their hearts torn out of their chests, literally).
I'm sure it had great therapeutic effect, though.
