I think you just have to stick it out.. its only for a relatively short period of time.
Remember there are 2 of you against her as it were, so perhaps sit down together and have a 'chat' about house rules.
In the meantime, don't let her upset you, keep yourself to yourself and cross off the weeks til you can move out
Its no
You moved in to her place, you agreed to pay electricity & she's a slob. Live out your lease & move, doesn't sound like you are friends anymore. In the future have rules in writing before moving in.
This is an interpersonal issue & there is really nothing you can do. Avoid & ignore her until the lease expires & move out.
Get the hell out of dodge
Put her dirty crap in her room. She wants to play games, be better at the game.
So I moved in with a friend 4 months ago and signed a lease for 6 months. Literally the first week we moved in she was leaving piles and piles of dishes for days and making massive messes and leaving her stuff everywhere. We spoke to her and she said she didn't realise and said she'd be cleaner. Nothing changed in fact things have gotten worse and worse as time went on, she brings her boyfriend over for 5 nights a week and he pays no bills or rent and they leave every light in the house on all night and all day and my partner and I have to pay all the electricity. When we confronted her she said what are you talking about he's only over once a week and she fobbed it off. She's consyantly playing instruments soo loud and has the tv on the highest level when we're home and when we ask her to be quieter she says oh I didn't know you were home but then continues to be loud. Dishes everywhere, her stuff everywhere. She moves our stuff and throws our stuff out if we leave one thing on the kitchen bench yet leaves her dishes and stuff EVERYWHERE. She made a communication board where she wrote requests on it and wrote tasks to do and all the stuff she was doing in the house it was like a boss us around board and she got angry when I took it down and said just speak to us properly! There's heaps more to the story but basically we're screwed and have 12 weeks left to live there without killing her or ourselves and we have no proof we payed bond ETc how do we survive and not get ripped
