Yet not with God. God's forgiveness is complete. Without variation. Our forgiveness is not. I can forgive someone. Truly forgive them. Then they do something or say something and what I truly forgave and released them from will flood back into my memory banks and I may experience some of the same feelings as before and have to forgive all over again. God forgives and forgets. Their sins and iniquities I will remember no more. As far as the east is from the west. THAT is forgiveness!
What if the 'someone' is yourself?
