It appears you seek reconciliation. That takes at least two people. Forgiveness takes one. Apparently you have tried to do your part in releasing and forgiving one who has hurt you. That he or she will not reciprocate does not dilute your gracious act. In the short term it may be less meaningful for you, for you want reconciliation, but the power of forgiveness will still be yours. Forgiveness, both giving and receiving, are a deep matters of the human head and heart. Forgiving takes humility. Receiving it takes greater humility.
