I also notice the frequent memory problems with my W. I test her memory when an opportunity comes along - and she always fails. I place items from her unfinished projects and put them into storage, she's never asked what happened to them. I put words into her mouth clarifying minor schedule details (never accusing her of anything), and not once has she replied with "I never said that".
All this seems offset with her OCD moments - activities she pursues with much energy & focus, only to quit and switch to something else shortly later.
Seeing the weird MLC behavior gives me a strange sense of comfort. It reminds me that I'm on a roller coaster, and I feel bad for finding solace in my sitch when I see my W struggling.
