Repost of room mate thinks she owns the place

Some basic details me and my room mate are both on the lease, paying the same amount. She has the tackiest style but I don’t care as long as I can add my own things. Mind you this happened because I said I wanted I put one piece of furniture out in the living room that has zero furniture at the moment. She ordered more furniture and never ran it by me but thinks she justified to tell me she can do whatever she wants but I can’t. I’ve told her I don’t care what you do as long as I can add my oven touch and it’s never been a problem. I’ve been blowing her u about cleaning the bathroom and she finally did it today now she’s using this to retaliate. She’s trying to gaslight me by saying she uncomfortable and violated, but this is the same girl who brings complete strangers in to our house cause she wants to get laid. She’s trying to say she never said I could not decorate but the proof is in the pudding. We had zero problems till I started asking her to clean up after herself and take accountability for her mistakes. I know we were probably both wrong at some points but I’ve been so respectful and patient I’m at my end.
