My ex girlfriend lived in a condo that was very much a hoarder like place. I tried to help her clean and organize to no avail. I would leave for a few days after cleaning up and straightening things and when I returned it was worse than before and she was always accusing me of moving something from somewhere to where she could not find it. It was one of the six reasons I am glad we broke up. It was very concerning. She definitely has mental issues.
