Forgiveness does not require any admission of wrong. If you insist that the other person admit wrong you aren't really forgiving, because you ignore the possibility that you may be the one who is wrong. Forgiveness does not even require that the dispute be first resolved.
I disagree. Especially with the 2nd sentence. Forgiveness requires you to blame the other person, you can't forgive someone if you don't think they're in the wrong. Accepting the possibility that you might be wrong has nothing to do with forgiveness.
