Ovr is completely right about no stress about moving out. If you decide to stand the timeline is years. 14 months from BD to XW moving out in my sitch.
You mentioned you co-own the house, as did I with my XW.
So what you need to consider long term, as part of a divorce, are you financially capable of buying her share? If so do you WANT to?
In the short term don’t make any moves befor consulting a lawyer and always from a position of strength.
