Dear Victim, what did they provide you that was so important to you that you tolerated that?
Accountability is a beautiful thing, and you should strive to take as much of it as possible. Without the acknowledgement of your own agency, you are paralysed. To say you did nothing wrong as a victim is a very dangerous cognitive dissonance because that implies there's nothing to learn from your experience. Bad things continue to happen to people who dont learn.
Now, the typical victim response to "where did you go wrong" is usually met with mental gymnastics reflection that indirectly bounces the blame back onto the perpetrator. Such as "my mistake was trusting too much" - "Im too much of an empath" - "Im too forgiving" implying that their fault is that they have an abundance of a positive trait that someone took advantage off. Being incredibly kind is not where you went wrong. And as long as you think that it will happen again. You tolerated it because they gave something to you that you thought was so valuable it was worth the abuse. Or you feared something was going to be taken away, and your fear preceeded your self-respect.
Did they love you even though you hate yourself and feared you'd never find someone else? Did your pride refuse to accept the reality that you failed and will have to start again? Did you lack skills and overly depend on your partner and fear you can't fend for yourself.
