I try to apply
it all the time, but apparently it is a dying kind of
dispute resolution.
It isn't a form of dispute resolution at all. You can't really forgive
someone until they accept they did something wrong (well, I guess
technically you can, but it doesn't achieve much), and once they've
done that, the dispute is already resolved. All "forgive and forget"
says is "once the dispute is resolved, move on, don't try and punish
people for their mistakes".
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.
