You cam detach while living together. It [censored] but its doable. I stayed in my marital home for 8 months after confirmation of my exwws affair. She treated me horribly. I dropped the rope and 100% focused on myself and my kids happiness.
You need to get to the point where you are indifferent to your WW.
I eventually mived out because my EXWW filed for D and it was over in May. I moved out June 1st.
Accept that your MR is over because it is. To truly detach you must truly do whats right for you. Do what makes you happy. Your WWs actions, desires and demands no longer matter.
