Divorce May Not Be the End

Some married couples never see their former spouse after a divorce. Many times that is because one partner leaves and never returns. There are other possibilities. Some former spouses may continue to reside in the same area and interact with each other, especially if they have children. One divorced couple in my family appear on a mortgage with a son-in-law after their divorce. Other times couples eventually remarry, even after they've had subsequent spouses. Or they may even later live together, even if they don't remarry. 

Those aren't made up examples---just situations from my own family where I've removed the names.
