After W moved out she would drop in almost daily just like she still lived there. It made things very hard, especially when she would leave to go see om. I finally told her that she couldn’t just drop in unannounced. She became angry and said it is still my house. I agreed and said she was free to visit anytime as long as she let me know first. That allowed me time to either leave or become busy. Mowing, cleaning the garage, etc. Maybe that can work for you as well. Good luck.
