Affair discovered 3

[STH17]

W has appointment near our house today and just texted me she wants to pick up some of her things from the house. NGS would say "sure, help yourself". But I don't want her going into my (legally our) house unsupervised. Tuesdays are busy for me, and I wasn't planning on being home today until late in the evening. I shouldn't have to change my plans for her convenience to pick up a few movies and other things she left behind. We don't have that relationship anymore. I think I will tell her I am busy and won't be home to let her in today. She has a key but the front door has a latch that can only be undone from the inside.
