She moved into the house I own on a handshake agreement - a specific rent price due on a specific day and one month notice before moving out. 

There were a bunch of red flags when she moved in (segregating the kitchen stuff so there were two spaces for everything) that grew into real issues (such as closing the spare bathroom door that her cat pissed in repeatedly instead of effectively cleaning it and eventually refusing to talk to me for the last several weeks) and early this week I told her we either needed to sit down and talk it out or I needed her to start looking for another place to live. 

She texted me today that she's moving out this weekend but would be in and out for the rest of the month - none of the notice that we talked about. 

I responded that she could have until midnight Sunday and that I would be removing anything left in the house on monday. I took no security deposit when she moved in and I need to find a roommate to replace her. She has a place to go and will be fine. 

tl;dr - roommate didn't give notice for moving out, so I gave her a shorter time frame than she gave me.
