Hi CW, I feel that is a simplistic definition of forgiveness. In reality, forgiveness is much more complex. If you are setting boundaries of no contact due to the prior actions of the other person, it means you are still affected by their actions and have not absolved them completely even if you choose not to be resentful.
But yes, if you go by that simple definition of forgiveness equating to not being resentful, I agree with what SteveLW said about forgiving for you and not the other person.
