AITAH for Banning Partners Sister Over Late-Night Habits?
AITAH for forbidding my partner's sister from staying over due to her disruptive late-night habits, sparking tension in the household?
Some people don’t recognize a favor, especially when it’s coming in the form of “sure, you can crash here.” For one guy, that favor turned into weeks of 2 a.m. chaos, and it blew up his relationship faster than he expected.
OP, a 35-year-old who works early mornings and goes to bed around 10 p.m., has been living with his partner for two years. But her 26-year-old sister started staying over in their apartment, and the late-night routine is brutal: loud TV, nonstop phone calls, and cooking at 2 a.m. OP asked politely, then got more direct after one especially noisy cooking night, basically saying she can’t stay if she keeps disrupting his sleep.
Now he’s stuck in the middle, wondering if he crossed a line with the sister and his partner.
Original Post
So I'm (35M) and have been living with my partner (33F) for 2 years; things are generally fine. Her sister (26F) moved to our city and occasionally stays over.
I work early mornings, so I go to bed around 10 p.m. Recently, her sister has been staying up late watching TV loudly, talking on the phone, and cooking at 2 a.m.
For weeks, I've been sleep-deprived and started feeling annoyed. I politely asked her to keep it down or sleep earlier, but she just laughed it off.
One night, after a particularly loud cooking session, I confronted her, saying she can't stay over if she disrupts my sleep. My partner thinks I'm unreasonable and her sister feels unwelcome.
It led to tension between us. I feel it's justified to prioritize my sleep, but was I too harsh by banning her sister?

That first polite request, from OP to his partner’s sister, got brushed off like he was being dramatic.

His partner called him unreasonable, and the sister took it personally, turning a sleep issue into a family feud.
