Why do some people take revenge on their partners while others forgive and forget?

The urge to take revenge when someone has hurt us can be very powerful. However, people often resist that urge and opt for forgiveness instead. In your essay, critically discuss the most important reasons that have been identified for resisting the urge to ‘get back’ at a relationship partner. Also discuss how factors such as personality and life circumstances might influence partners’ decisions to ‘forgive and forget’ rather than take revenge.
