It seems like mil has been in the same crazy loop forever. There are days when I wish she'd advance to the point where she no longer knows us but I guess that's mean. After three years she still accuses FIL of cheating on her everytime he's out of her sight for even a minute. She has been at stage 5 for about 2 years. Some days she's a 5.5 . We first noticed there was definitely something wrong about 4 1/2 years ago. But looking back before that there were signs in her personality. She still has super energy.
