Hi PLP,
I'm sorry you're feeling so alone
I agree with Fie that it's much more likely your D is projecting her intense self-loathing onto you. She may also be angry that she is allowed to behave in ways that perpetuate her internal image of being a bad person. In other words, she blames you for letting her act badly instead of taking responsibility for her own actions.
We can interrupt this loop when we no longer allow the abuse. There are many counter-intuitive skills that can help, and people here are all learning as we go, making things better one small interaction at a time.
"I see that you are very angry at me right now. I'm going to give myself a timeout to get centered so I can take in what you are saying. I handle this kind of information much better when I am not off balance." -- is one approach when your D dysregulates and points the firehose of rage your way.
Always take care of yourself so that you have the strength needed. Like Lollypop says, all we can do is change our behavior and how we react.
It can have a domino effect.
