Hey native, Sorry to hear the change of events. No, you don't sound petty listing her shortcomings - it's good to get them out & here is the best place. I think we all come to the fork in the road you have. You continue to grow, while she seems not to be able to & thus keeps herself in the vicious circle of the same actions.
I, as a matter of fact came from a divorced home. My parents divorced when I was 3. Back then, in the 70's divorce was not common - so in a way, I always felt like an outsider. The best thing you can do for your D (& you are doing this) is be there for her to share her feelings with you.
I'm at a loss for words at the moment - maybe later.
Stay strong & work through the anger you have. Don't let the anger pull you down & control you.
