oops sorry, don't know why that posted then. Meant to say, he couldn't get through to her the day before. And she was telling me it as though it was some great victory she'd won over him. She's had so little power in her marriage, that she grabs at any small victories that present themselves to her. 
But then OTOH as she gets iller, I worry that he'll have what he's always wanted, which is total and complete control over her with absolutely no escape for her physically at least. And all the while, he gets to present himself as her loving, devoted carer. Which of course, he is as well, by his own standards.
He's also finding that he has to learn to do things he's deliberately never learned to (ironing, how to turn on the washing machine etc.) and he's been surprisingly OK about that; I think he feels it's justified as she's ill, but the odd thing is that he still expects her to do the laundry when she's having a good day (and she wants to, because she feels that's her remit and she doesn't want him muscling in on her territory; he claims she gets annoyed with him for doing the laundry and I do believe him, because I think for her, those everyday things are symbolic of her hold on normality).
Anyway, rambling along, the upshot is, it's all very complex and sad even if you have a happy, fulfilling, functional relationship. When you don't, it's a massive can of worms which I'm only seeing a tiny bit of.
