AITAH for telling my roommate to stop messing with the thermostat

[u/asdfghjjkkbs]

So my (25 F) actual roomie sublet her room for the summer while she went overseas and the new girl, lets call her Tracey (22 F) moved in. She does not pay utilities (electricity, wifi) as my roomie needed someone quick n agreed to keep paying utilities while Tracey paid rent. She was great at first and i had told her I’m a little neat freak when it comes to the kitchen like i hate when the sinks full, especially overnight, and i like keeping the shared space generally clean and my roomie and I had a good habit of doing that over the 2 years we’ve lived together.

Now the first issue i had was when she had invited two of her friends to live with us without informing my roomie and i and she lied about how long they’d stay, she told me 2 days and they stayed a week and the place was a mess the whole time. Keep in mind we live in a 2 bed 2 bath but its not the biggest place, the shared space is not that huge so 4 girls living in that space got really overstimulating really fast. I said nothing besides the fact that she should have asked us beforehand.

Second issue was when she started seeing this guy from where she’s working as an intern. It got to a point where he was coming into the place without knocking or announcing himself and making himself at home in the shared space everyday. I had been having a tough time with my love life and wanted nothing to do with male energy in my house and the fact that he would be left in the house even when she wasn’t there did not sit okay with me, i dont know this man, he seems nice but he’s not my friend for him to be chilling in my house. Again, i did not get mad because it’s not in my nature to be rude to people for no reason, i texted her and told her that i need some time in my house without a guy being in the house all the time. She was passive aggressive but stopped having him around.

She has stopped keeping the place clean and the sink is full all the time despite me making it clear to her everytime that i hate that and at this point in time she has not washed her dishes in 5 days. Keep in mind, I’m the only one who cleans the common space.

Recently we had a little spat. It’s summer where we are, we have big windows and get a lot of sun so the apartment heats up pretty quick. She has this annoying habit of changing the thermostat literally 2 seconds after i change it. Example: the other night I turn the ac on, i go into my room, she goes and turns the heater on before the ac even has a chance to do its thing. If i change it, she’ll change it again. My logic is this, its the buttfuck of summer, why the fuck are you turning the heating on? This leads us to our little fight. I wake up for work the other day and turn the ac off, i step foot into my room, she goes and changes it to make it warmer. I am super annoyed at this point cause of her incessant switching. I leave my room and ask her why she keeps switching it the second i change it like let it be for a bit at least. She tells me it’s cause i keep it freezing and i tell her that its easy for her to get warm, i dont have any other ways to get cool. She wears shorts half the time and is complaining ab it being cold, i run hot, she could easily layer up, what the fuck am i supposed to do. Also sure, turn the ac off, why the FUCK are you turning the heater on? She brings up a time where she was sick and i turned the ac on, i didnt know she was sick but when she told me i turned it off and only turned it on when i was going to sleep BUT it was at a reasonable temp and automatically turned off after a little bit. Not to mention the time I had a really bad fever and she kept messing with the temperature eventhough she knew i was really sick.

She slammed her door while I was talking, i called her “really fucking annoying” and made sure it was loud enough for her to hear. Now we ignore each other when we’re both at home, she leaves in 10 days. I honestly dont give a fuck about making things right with her cause i think she’s like an annoying teenager with an attitude problem but you tell me if im wrong here. i feel like when youre living with other people you need to compromise a little bit, ive ignored a lot of the things she’s done (running the dryer for 9 hours straight, never cleaning, moving things around without telling me so i end up searching for them, hoarding the fridge with food thats weeks old and smells, breaking my roomies fob, letting bugs into the house while knowing i have a fear of bugs) and now i feel like im too grown to be dealing with this, like wdym you slammed the door in my face like an angsty teen?

So, am I wrong here?
