Do you think she sees you as the surrogate spouse?
I don't know, maybe? She's an odd mix of ineffectual and incompetent, and very stubborn and "resilient" in that she built up a life for us here in the UK and helped various friends out in various ways.
I'm usually a calm person but she makes me lose my temper often. She will never drop things. I can't just say stuff, I have to shout at her and then she will say "ok ok daughter, you don't need to yell, I understand".

It’s very easy to regress with parents. I wonder if you felt responsible for her safety even as a small child.
Oh absolutely I did. I can't even tell you how much I tried to make her leave when I was young and naive, I wanted to fix everything and I wanted to lock my dad up and then we could be happy. I can't to my senses as I grew up and that's when I started to pull away, emotionally. I remember someone saying to me once, off-handedly "some people can't be saved". I feel very conflicted about that: some days I think this applies to her, other days I think I can stride in and fix everything. But I don't understand how she thinks and she tells me to be quiet, not say anything, not make things worse for her, and I retreat back into myself, feeling paralyzed and furious and like a failure.

Op this is called Triangulation.
I've never heard that phrase before; do you have any links I could read up on?
Your DM is drawing you into the toxic relationship so that you are made to feel responsible for her emotions but also feel FOG
Fear, obligation and guilt.
Stately homes thread in relationships is great and will be helpful.
I fear for her safety, I feel obliged to help her somehow, even though I think i end up making things worse, and I do feel guilty for "leaving" I suppose.
I've seen that thread referenced before, isn't that for kids who were abused? I was never abused, the worst I ever got was a smack every now and again for acting out.
