He doesn't remember moving things but he does it all the time, including things I have on my desk. He claims he's tidying up but the former family room which he uses as a hangout is a total pit. I've tried to help clean up that mess but he just keeps putting things back in piles all over the furniture, floor, and tables. It got so bad that I fell while trying to get to the window, which resulted in a large bruise on my thigh that took a month to clear up. He seems oblivious to my concerns and thinks I'm picking on him.
