She doesn't have a key. The accommodation has never been lived in by her and my partner (her ex), but we knew that his daughter (who is 31) was coming to have a meal, just before Christmas and her mother was visiting a friend nearby, so they were travelling together, but she decided that when I said "come in" thinking just the daughter, she walked in too, and I'd like to stop her thinking she can do this, my reason is that my partner seems to have contact with his daughter quite often behind my back,. and wherever the daughter goes the mother seems to be in tow. My ex was embarrassed and said he'd divorce her so that she hadn't got as much hold over him.
Nothing was said, I was by then walking away and in the kitchen preparing the meal, I don't know what was said to her, she put down a Christmas present for my ex that's what I saw and a few words I noticed but I don't know what was said, and then she went.
