"Forgiveness does not always lead to a healed relationship.
Some people are not capable of love, and it might be wise to
let them go along with your anger. Wish them well, and let
them go their way."

Another idea..
There are people who can't truly give and forgive. But never mind if they does, pray for them. Because the people who withheld what they must give away posses inner ill in their feelings.
