To let go of the outcome is truly at the crux of being authentic, truthful and real.
An example of this is that I recently confessed to old A's to my H. Before I could do this, I had to get through the terror of the possiblity that it would be too much for him and he would leave. Once I let go of the outcome and realised I had NO control over what he said or did, was I had the strength and courage to be truthful.
It is a freeing thing to do. And although not perceived at the time, an act of love for the other person, as well as the self.
It also means we can maintain solid boundaries with others, as their response or actions are out of our control, but we DO control what we do and how we live.
It is a standing up for the self, and maintaining a core of integrity and self respect.
