Forgiveness is part taking control and part letting go and part accepting reality. It's not about the other person. It also doesn't mean you don't make any changes in your thoughts or behavior or adjust to the reality of whatever it is that the person did to need forgiveness for. If you were mistreated as a child, you can forgive the person who did it. But you'd be irresponsible to then just send your own kids over to that person's house or let them be a primary caretaker of your children.
