R2C thanks for your detailed thoughts a few posts back, that is really helpful input.
Regarding the MBR, yes I am in it and W just moved to a guest suite after her sister and her husband cleared out after visiting for Christmas. W wanted the MBR for the IHS, I told her I was not moving out of the room and that we had 2 other empty bedrooms to choose from. She was seething. Truth be told the guest suite she is in now in is huge and pretty awesome, friends and family joke it is better than the MBR, but I get the symbolic nature of me asserting control over the MBR. It was easy to do as I am Alpha and the more agitated she got the more calm came over me.
W really wants me out of the house but I told her very calmly and assertively that I have not decided what my plan is as far as future living sitch and that I am not moving right now and perhaps not at all. I told her she is free to do whatever she needs to do to get her space, including moving out herself. This led to a brief discussion regarding future plans for the house, which we both want and both agree would be best to keep for the kids as it is the only home they have ever lived in. The issue is going to be the buyout as we have owned the home for 7 years, bought it at the bottom of the RE crash and we now have massive equity. To be continued on this front.
