Not to the same house but a house is just bricks and mortar, it just a house just like the millions of other houses out there.
Is there turning back?
Yes, it gives you a chance at R but you need to loose the bad sitch you are in now to have the possibility of going back to a better MR.
What you will have with out the current house is a chance for a new start. A hope that with so much shaken up and change that what's left is all new. A new beginning. The unhappiness that your wife is feeling can not be blamed on the living sitch anymore. It cannot be blamed on you for keeping her in this sitch anymore. It allows you to be free from the blame and then your W will be left to see the unhappiness was hers to own.
Do what works and change what doesn't. Living in house S is not working for you, for as hard as it is you need to change it.
This is not Divorce.
This is Separation.
Let W file for D if that is what she wants. If you don't want D you don't file.
