Well Mike, I'm not sure what to say about this. If your suspicians are right then that would explain alot about her actions right now. How long has the sickness been going on? You stated she has weight gain also, remember that everyone handles stress in different ways, some stop eating and others start eating more. I would do snooping tomorrow morning, I would have to know this answer.
I can tell you when I was reading what you wrote, the first thing I thought of when your W said she was with MIL from 8-2 was basically because she was trying to take control of the day from you and making you go and get 4WD on her terms, not yours. This was just my impression until I got further into the thread.
