Answer:
The husband's actions would be an example of avoidance behavior.
Explanation:
Avoidance behavior is characterized by actions taken by someone with the purpose of avoiding stressors. In Diane's husband's case, the stress is Diane and the way she has been mistreating him. Instead of dealing with it by talking to her, for instance, her husband would rather avoid the bad feelings and thoughts generated by the stressful situation. He takes action to stay away from her and to protect himself.
