I can say in my case, I've had 2 lucky business trips that have taken me away for 2 or 3 days at a time, and I have left for a day or 2 on the weekends as well (at her request, by the way).
So I've been able to give her space while living in the same house.
Do you do individual counseling? I gather from your posts that you may have a very difficult time accessing your feelings. You think much, I suspect you feel little.
Have you been sexually abused?
