Thanks for the words of support. Based on your experiences, this is something that I need to be very patient with.
Cold - it is reasurring to hear words from someone who is in the same position as me.
My wife still works with the OM and like your situation, my wife comes home on time and things seem to be moving in the right direction. What she does at work is out of my control, so I need to block this out of my thoughts. You can waste alot of time thinking of all the things they maybe up to during the course of the day.
I recognize that my wife will need to go through a period of grieving and it seems that this will likely take many months.
Keep me posted as to how things are going with your wife and if you see signs of the fog lifting.
