Oh OP, that isn't how domestic violence works at all.
Have you ever heard of the freedom programme?
You stay out of fear and confusion and guilt and shame. I know that the general public view on this topic is very much...you should have walked away...
Hindsight is a wonderful thing, except where at the time you were so traumatized and trapped that you couldn't tell up from down. So you freeze like a rabbit in the headlights, until something so bad happens that you act to survive.
You don't deserve to be carrying around that shame. That shame belongs to him. You were a victim of abuse.
You know, even though he raped me, he was in our lives for years. He would apologise, threaten suicide, then be nice and I would be so confused.
It took him injecting them with insulin when he was hypoglycaemic, so I had 3 people all in hypo at once, for me to do something. SS got involved and my poor kids had to speak out and say they didn't want him in our house.
Even then, he was so good at manipulating me, it took SS putting them on child protection and me on pre-care proceedings, before it finally got through to me on any meaningful level.
He was ultimately assessed as high risk by both SS and a psychiatrist, so I was able to finally NC him. I also got another non molestation order due to continuous attempts to manipulate me. I am immune to him now. Finally.
You were not you when you were trapped in that hell. What matters is that you found that strength, you got out, and you adore your daughter whoever she is right now.
I'm not saying don't mourn what could have been, I'm saying, lay that shame at the right door.
