I frankly think "responsibility" is the wrong word for this. She maybe made a mistake out of ignorance, she maybe was confused by the abuser (abusers do that WELL), etc. etc. But the abuse was not her responsibility. That's definitely victim blaming and unfortunately some victims can blame themselves like this and it prevents healing.

And I am saying that while agreeing with you that you do need to get to empowerment in the end, from first accepting that the abuse happened.
