" Stages of becoming a forgiving person
In the first stage of becoming a forgiving person, people experience a loss in their life, feel angry or hurt, and tend to justify their negative emotions. At this stage of forgiveness you are filled with self-justified anger or hurt.

At the second stage you choose forgiveness once in order to hurt less.

At the third stage you choose it daily to hurt less.

At the forth stage you become forgiving so your choice is already made. "
