Your AITA post tells a lot. You moved in to your boyfriends flat to help him pay rent.

You both then got a roommate as you needed help with the rent. BUT you were conveniently not present at the flat viewing so the new flatmate had no idea they were moving in with a couple.

When they realised they asked to split the rent 3 ways but you were firm that you wouldn't be doing that because you shared the room with your boyfriend. Then you posted to AITA as you apparently couldn't see how much of an asshole you and your boyfriend are.

"So the rent split was 25/25/50 because my boyfriend and I share a room and I'm basically just there to help him out. We split the bills into 3rds. I'm very clean, quiet and I make the house look nice and smell beautiful! I am a very positive person."

"About a month in she asked how long I would be staying for and my boyfriend answered for however long that I cared to. I told her I was looking for a place and should be moved out for January/February. She asked if we could split the rent into 3rds and she was met with a no."

"She has now brought it up again, three months later. Quite aggressively. I've told her no, once again. As I'm just trying to make sure we have somewhere to stay until January. She sees it as she's paying for me to live here which I don't understand as she has signed her agreement."

I'm sure she just binned all the plates and cutlery because she was just so done with you both and I hope the police do absolutely nothing.
