I want to break up with someone but we’re both snowed in and she won’t leave

Let me explain, I have my sister and her 2 kids (my niece and nephew) living with me. She used to live in another country and I told her I’d support her if she came back to the US and so she did. So basically my house is. I live in the basement. My sister lives on the main floor. My niece (8) and nephew (10) live upstairs. <br><br>So my GF and I had been together 10 weeks and she was really awesome until she came to my home for the first time. She went full Karen over all sorts of things that honestly I think are not that big of a deal. Like, she went up to the room where my niece and nephew sleep, opened the closet to look around, and found a picture of her boyfriend with my niece and nephew. And went absolutely nuclear. I tried to explain it’s not my home, my sister and her 2 kids live there, and the guy in the picture is my sister’s ex-boyfriend, not mine, and it was taken years ago at a Christmas dinner when the kids were 4 and 6. She refused to listen to me but instead, she dragged my niece and nephew into it and asked them all these questions about the picture, and who took the picture, and if the guy in the picture still lives with us or if he ever comes over and stuff like that. <br><br>And the thing is, she didn’t do all this immediately when she came over. She was really nice and wonderful for a couple hours, and then out of nowhere she just started screaming at me and then my niece and nephew. It was like she was totally different. I was like holy shit, this woman is fucking crazy. I told her to leave and I drove her home. And after I dropped her off, I got a bunch of text messages and voice mail from her. Then the next day, she showed up at my doorstep with a suitcase and said she’d decided to move in with me because we’d been together for 3 months and she felt like it was time. <br><br>I don’t have the energy to type out everything that happened but basically, my niece and nephew told my sister what happened and my sister freaked out when she heard that. She told me not to bring the GF to my home again and said she didn’t feel safe having her around her kids and that I was putting them in danger by seeing her and bringing her to my home. I completely agree with her. I told my GF I wasn’t interested and to please leave me alone. <br><br>Well, I have an air bnb I set up as a mancave to get away from the house and she showed up there and refused to leave. I have been with her for 10 weeks. I didn’t tell her the address and she knows full well she’s not welcome at my house so I have no clue how she found out the address of my air bnb. It’s not like I’m rich or anything. I work hard for my money but the air bnb is just a place for me to get away from home sometimes. I really don’t know how she found out the address and it really creeps me out. <br><br>I stayed at a friend’s home and she came there and pounded on the door and the windows and shouted at my friend when he came outside. One of our mutual friends told her where I was. She’s been showing up at all my regular spots - the coffee shop, the park, the brewery. Any place I go, she shows up. <br><br>I finally decided to go back to my air bnb and she followed me there. I tried to walk away from her on the street but she followed me to the door. She got in my face and started screaming at me and I got in my car and left and she ran down the street after me. <br><br>So now we have a snow/ice storm and I decided to stay at my air bnb just incase she shows up at my friends house again. So when I woke up this morning, there she was. Standing in the living room. And she refuses to leave. Initially, I thought she must have broken in and I was like oh shit, she broke into my air bnb. But then she started talking about how she had asked the landlord if she could move in with me and he said it was okay as long as she paid extra and she paid the extra and he let her in this morning. <br><br>The landlord knows she’s not my GF. He knows I’ve been trying to avoid her for weeks and he knows she’s been showing up places and scaring me. So I don’t know how he could do this. I don’t know what to do. I don’t feel safe being alone with her because she’s mental. I will do anything to keep my niece and nephew safe and it’s just me. My sister doesn’t know what to do because she’s worried about her kids. They’re already devastated by her ex-boyfriend. She doesn’t want them to find out about this crazy GF. I really don’t want to call the police unless I absolutely have to because of the potential repercussions this will have on my niece and nephew. <br><br>I’m going to tell my landlord to come over and get her. I’m going to tell her I don’t want her there and I’m going to leave and go stay with a friend and call the police if she follows me. But if she’s paid rent, is she breaking and entering if she refuses to leave? I don’t know if they consider that breaking and entering in a situation like this. But I’m also somewhat blaming the landlord for letting her in. It’s not normal behavior and he should have known that. <br><br>I’m not going to sit here all day and wait for her to freak out. I’m going to leave but I wanted to get some advice first because this is just so nuts. I honestly wouldn’t even believe me if I heard this story.
