“When a deep injury is done us, we never recover until we forgive.”

This quote implies that in order to forget you have to forgive. You always have to choose what is better to do not easier. You need to cope with the situation in the best way possible. You always have to choose the right and do what is right no matter the consequences. When you want to heal you have to forgive and forget. You need to understand that it's the best thing for you and for the other person involved.
