I have been thinking about this since you brought it up. At this point in time, and now that I know all I do(mostly about me)I can't ever see letting anyone (even someone I love) putting me through that. I think this time I would be the one running rather than to put up with that kind of behavior.
When I go back in my mind to that point in time we are different people. Not much more than a shell of ourselves because we have no idea what's happening, so we say and do a lot of things that looking back now seem incredible. Although I didn't have to put up with that, I can understand how someone might think that they have no other choice. Most of us are just not strong enough to fight back at that point.
Believe me I can understand your amazement, but you are a survivor and they have yet to walk through the fire.
