When there is no remorse from the other person there is nothing to forgive. When they think they are so perfect that there is no remorse for the hurt they cause. One can just leave the person & have nothing more to do with them....& let go in that way......it has nothing to do with being super-perfect in one's self.....it's the other's one belief of perfection that causes the non-forgiveness......& the need to go on with one's life in a different direction.
