Ok so this is alot to unpack. I recently had a nasty falling out with my (now) ex best friend. We had been living together for 8 years as we moved to a new city together for Uni. So the falling out erupted because I had had enough of her sloby, lazy behaviour and also finally brought up how she had been sneaking men (ALOT of men) over the second I left for work. I found out pretty much straight away because the cat camera we had set up for both our cats in the living room also showed the front door. For context, we had a set in stone rule that you MUST ask before bringing someone over. Anyone, for any reason. That applied to both of us. The purpose of the rule was to ensure each of us felt comfortable and safe in our own home and to (in theory) prevent arguments. So I brought up the sneaking of men over in an 'I've had enough' kinda way as this had been going on ever since we moved into this place in Nov 2024. She litterally ran to her room, slammed her door as hard as she could and stayed there. 3 days passed and she would only come out when I was at work to sneak something to eat then hide in her room again. And she was trying to make it look like she hadn't been there. I know this because I regularly check the cat camera at work to see if my cat was being an ass. I tried to bring the situation up again in what I thought was a non-confrontational way, however she absolutely exploded. (I can be very blunt without meaning to so that one might be on me) She started screaming at me about how im so controlling and she can never do anything or bring anyone over. Incorrect. She always had people over multiple times a week. Without asking. I would like to note that she regularly told me I couldn't have someone over. I could probably count on my fingers how many people I've been allowed to have over in the past 8 years. But I had made it clear multiple times that if she were to ask to bring f*ck buddies or one night stands over, the answer would be no. And her having a, let's just say, a vibrant sex life, didn't like that. And when I say vibrant I mean nympho like...

Now this kind of reaction is typical for her. She cannot handle confrontation and tries to just hide it out. Like, litterally hide. In her room. Her record with me is just over 3 weeks. And if an actual verbal argument occurs she just screams. Not yells. She screams at the top of her lungs to the point her voice gets all scratchy. So that's what ended up happening on the last day I saw her two and a half months ago. She screamed about how controlling I am and that I have "3 f*cking months to get out" as she left. Haven't seen or spoken to her since.

This is where the problem is. The house I am currently living in (not for long, I'm moving in a week) is a sublet from her boss. (he leased it through the agent and we lived here) I am not on any lease agreement nor have I signed anything. Despite asking. Though she is on the lease as a subletter. This entire living arrangement has been in her full control. I was denied any and all information about the place I am living in. And the only way I could pay my share of the rent was to allow her to access my banking account to send the money to herself. After that I dont know where it went. It wasn't until the damn owner showed up for an unscheduled chat that I was finally able to give my contact details which she passed on to the agent and I was finally privy to 'some' information.

As per her screamed instructions, I am vacating within my 3 months. Her father is heavily involved in the situation as she can't deal with the consequences of her own actions herself and her parents are paying her share of the rent for this place in full so she can rent another small apartment. (another repeated behavior is running to mummy and daddy when she screws up and waiting for them to fix it) The plan discussed in the begining with alot of back and forth between our parents and us was that the lease would be terminated. Don't know where the readers are from but in Australia you can't just break the lease and leave. You have to pay fees and keep paying the rent until a new tenant is found or the lease term runs out, whichever comes first. The lease holder and my ex friend have waited until yesterday (2.5 months) to ask to break the lease. They should have started this proccess immediately. Now the father is demanding that I pay the break lease fees (roughly $600) and continue paying my share of the rent until a new tenant is found. Here's where I say Get F*cked!. She is the one who couldn't have an adult conversation about her own shitty behaviour, she is the one who just moved out without notice and left me essentially squatting, she is the one who demanded I be out in 3 months, she is the one who wouldn't let me be on the lease or sign anything. So I say, she can deal with it.

These last 2.5 months have been absolute HELL for me. Not knowing what's happening with the place I'm living in, getting constant emails about being in debt because her share of the rent hasn't been paid, the agent blaming me for the lease holder ignoring emails and more..

So this is where I ask AITA for refusing to pay anything after my last week of rent?
