Her saying "You broke me" is akin to absolving herself of any and all responsibility. She is saying it is ALL YOUR FAULT.
She takes no ownership of her actions, after all you broke her. All her rotten behaviour is your fault, after all you broke her. She doesn't have to be accountable, after all you broke her.

That is outright emotional abuse.

Abusive people are notorious for blaming the victim for the abuse they receive. The victim made them do it. It's the victim's fault.
Dinner was an hour late. That's disrespect.
They forgot to bring me my beer when I asked for one. That's disrespect.
They watched porn. That's disrespect.
Therefore, I am fully entitled to mistreat them any way I want.

If I am emotionally abusive, they deserve it as they disrespected me.
If I am physically abusive, they deserve it as they disrespected me.

The "disrespect" is simply an excuse for them to abuse another.
