For me, the running away, was the fear of telling...the fear that what I was told would happen, if I spoke, would occur and that would be my fault. That was my free will as an adult. And the other place free will comes into play, no it was not my free will, nor my Mom's, but the free will of my abuser.
Your article is on point about body memories. They never go away. Our only defense is to be aware of them and learn to recognize them so we can change our responses and reactions to them. I now know the dates, time frames, phrases, and experiences that most often trigger a body response. That gives me the strength to make choices against my abuser no longer having a hold on me, all these years later. That is the soul (yes play on words) reason I don't run away anymore.
