Is NOBODY wrong in the post ? POST : To clarify, it's my house and she hasn't signed any form of lease agreement. 
A couple weeks ago I confronted her, saying I had been getting the vibe that she doesn't like me anymore. She admitted she had been feeling that way. I was hurt but didn't press her further, telling myself she must have just felt like that for a while and gotten over it, or she would have moved out. 
Last night she told me over Facebook messenger, while we were both home in our separate bedrooms, that she was moving out. I told her to take as long as she needed. Then I took the opportunity to ask her to clarify what she meant when she said she didn't like me. Her response was that she had felt like that since she moved in which was the beginning of January. 
I thought about that all night and then I told her this morning that I wanted her to leave immediately. I said she could take as long as she needed to get her stuff out but I don't want to share my house with someone who doesn't like me for one second longer. I feel betrayed by this whole experience and it's been really affecting me. 
I just got out of an abusive relationship and I'm grieving cos my brother died in December. I'm upset that she stayed in my space this whole time, making me feel awful and uncomfortable, not being upfront about issues and letting them fester. 
She's now trying to say she only meant she didn't like living with me. But that's not how she put it the three other times we spoke about it. I think she's just trying to back out of it. She is calling me unreasonable for not letting her stay tonight, even as I'm telling her this is testing my mental health. I have been hospitalised 7 times in the last 6 years and am now stable and this is jeopardizing that. To which she responded, this is stressing me too and it's not all about you. She has no mental health issues. 
So am I the asshole for demanding that she leave my space immediately?
