She has shut down completely. I have done some snoopng trying not to do that any more. She will finish work on a friday and some weekends only leave her room at her mothers to eat and use the restroom. I believe at this time she is just overwelmed with life i guess. Also the difference in her overal look she will wear same outfit multiple days and has looked very un kept for the last few months. She visits and calls no one except her kids.
I understand why you asked that question but i dont thi k we are on that path yet.
Since you've added this I'd have to say there may not be an OM but that she has very serious depression, maybe clinical depression. It's a time like this in the marriages vows ("for worse..." "in sickness...") that you have to be a rock for her even if she pushes you away. You're the leader of your family. You have to lead the way through this crisis. She needs professional help.
