There is such a big difference between forgiveness and reconciliation. It takes two to reconcile, so it is not always possible to be reconciled. But it takes only one to forgive. So if people do you wrong, forgive them, whether or not they ask for forgiveness. You cannot cancel their sin. Only God can do that, and He will only do it if they repent. But what you can do is set aside your own anger, bitterness, and resentment towards them.
