In my situation, I chose to move out to an apartment so that WAS could come back to house from a hotel. This gave me a chance to re-establish my own independence. Two things I've observed: (1) I packed up and moved all of my belongings to storage, but most of my clothes I chose to no longer wear, buying new clothes that I picked out myself; (2) W emptied the house of all photos, bought a bunch of new clothes for herself, and repainted the master bedroom.
I've heard before that following a breakup women do things like cut their hair as a symbolic breaking ties gesture for themselves. I think my W's actions with the house are similar.
