Everyday is a new lesson for us to learn and grow. Forgive and forget is one of the hard one for us. I still remember when I was studying at University, one of my brother in Christ had shared this with me "Forgiving without forgetting, it is not a true forgive".
So I guess...
Forgiving is allowing another person to be human for faults, mistakes, or misdeeds. Forgetting is putting these behind you; they are no longer brought up and no longer remain a barrier to your relationship.
Forgiving is letting another know that there is no grudge, hard feelings, or animosity for any wrongdoing. Forgetting is the lack of further discussion, with no ongoing negative references to the event.
Forgiving is letting the other person know that you accept as genuine the remorse and sorrow for actions or words that hurt or disappointed you. Forgetting is promising that this deed, whether of omission or commission, will not be brought up again.
Forgiving is accepting the sincerity of penance, sorrow, and regret expressed over a grievous personal offense; making it sufficient to clear the air. Forgetting is your commitment to let go of anger, hurt, and pain over this offense.

Forgiving is the act of love between you and a person who has hurt you; the bandage that holds the wound together long enough to heal. Forgetting is also an act of love; in rehabilitation therapy, helping the wounded return to a full, functional, living reality.
Forgiving is the God like gift of spiritually connecting with others, touching their hearts to calm the fear of rejection, quiet the sense of failure, and lighten the burden of guilt. Forgetting is the God like gift of spiritually touching others' hearts with the reassurance of a happy and full life with no fear of recrimination, remonstrations, or reminding of past offenses.
Forgiving is the act of letting go of temporary ill will, disappointment, or the disgust that arises from the break in your relationship. Forgetting is bridging this gap in the relationship, eventually strengthening it against such a break in the future. (from coping.org)
