Tad, continue to think of her as a toddler. They say things over and over again to convince themselves, not you.
Grown up people tend to say things once, and they may repeat it if it hasn't gone in. Endless repetition is a sign that they are telling themselves a story, not you. This is not for you to pin your hopes on though, she sounds like she has a journey to make, and you are better off without her at present, hard as that is to believe. You are still hoping that the fog will clear and the 'old' person will emerge, and all will be well, like a bad dream.
That is not the way the MLC unrolls.
There is a lot of misconception about 'understanding' MLC. If you think of it like an illness: accept it exists, and that it has its pathology. You may find it useful to understand this. So for example, I got cancer a year ago. I didn't ask 'Why did I get cancer' but I did want to know about the type and what, if anything I could do about it, and how I could deal with it.
Your wife appears to be in MLc. She will do and say the most extraordinary things, because she is messed up. If you analyse what she does you will feel as if you are going nuts, but on the other hand, if you can recognise it as crazy MLC behaviour it may help you to tke it less personally.
The correct answer, if you have to respond, is "You have told me already."
