What if a spouse is left particularly angry?
There are many people who don't want to let their anger go because their anger becomes their purpose for living. A spouse who has been maligned, who has been asked for divorce, may decide that she or he is going to spend the rest of their life paying you back for the pain you inflicted on them. That person is going to feed off the anger, and it's going to become a purpose in their life. It's going to become a cause, and what happens is if you take it away, they don't know what else they have in their life.
