Does there come a point when forgiveness should no longer be given?

the whole concept of forgiveness is not about others. forgiving each other serves as a reminder that we must forgive ourselves in order that we may grow.when we give up on others then we give up on ourselves.who are we to demand that others must change when we decide,who are we to set conditions on forgiveness? when others seek our forgiveness it often shows they are unable to forgive themselves and that is truely what they seek.
