Man doesn't want GF's sister sleeping in his bed; says, 'my house isn't a hotel.'

'AITA for not allowing my girlfriend's sister to sleep at my house?'

I 26M have been with my girlfriend for a bit over 2 yrs. We live separately but she's been spending most days at my house. I eventually gave her a key to my place. I'll come home from work and most of the time she'll be there.

She basically lives there. Has a lot of her belongings there,showers, sleeps there,etc. She has 4 sisters. 2 younger, her twin and her older sister. Her older sister has a 2 yr old daughter and is a single mom. My girlfriend has been asking if her sister could come to my house to hang out. I have no problem with it so I say sure.

Here's the problem. I got home Thursday. When I got inside my girlfriend was with her niece. I greet my girlfriend and niece. When I start walking to my bedroom, my girlfriend tells me she set out clothes for me in my gaming room. I ask why? And she says that her sister is taking a nap in my bedroom.

I'm taken back by this and say ummmm no yea she cant do that. My girlfriend asks what I mean. I tell my girlfriend that not only is it rude to sleep in others peoples beds but this is also my house, so I won't be quiet either.

My girlfriend explains that her sister is burnt out and needs a break. I told her that's fine and everything but she can't be sleeping in my room, on my bed. That my house isn't a hotel. I could sense my girlfriend getting angry. She's one of those types that is a silent angry.

She simply gets up, tells her sister to get up. They gather their stuff and she leaves with her. She calls me back saying that since my house isn't a hotel, she won't be staying there with me anymore. She tells me that her sister seriously needed a break and I couldn't help her. She hangs up before I can say anything. I'm having mixed feelings about this whole thing but feel I could've handled it better. AITA ?

Here's what people had to say:

NTA. Your girlfriend sounds like a teenager. You don't give her age, so I'm not sure if she is one but if she is, this is what happens when you date children. If she's your age, she has no excuse acting so immature.

She's 28

INFO: are you both from different cultures? Asking because in some cultures it would be totally fine - not as big of a deal and would be considered part of the hospitality to let the guest nap/sleep in your bed if you don’t have other rooms in the house. Also - I am not saying that is right or wrong, just curious if that’s the case.

Yes. She's from Uruguay and I'm from the US.

Yeah, I only learned the whole 'bedrooms are sacred' thing from Reddit. I would consider it totally normal for someone to crash in my bed while they were visiting my house and I'd do the same (and I'm from Canada though I've lived abroad a lot). I'm sure it genuinely didn't occur to her that it would be a problem. I think this is more of an 'NAH cultural misunderstanding' situation.

You don't seem particularly upset about losing your girlfriend though so you're probably both better off without each other.

I am upset, I just can't really express it

NTA. Now you know your girlfriend thinks of your place as a free hotel. Might want to seriously rethink what your relationship is.

dontbeshy007 OP responded:

I am. We never ran into problems before but she's showing her true colors.

NTA - I'm the only one allowed to loan out my bed.

For real I was like 'when did it become okay to sleep in other people's beds'. I'm cool with her sister but we ain't that cool.

Your girlfriend is being very disrespectful to you and your space. And that fact she is giving you the silent treatment because you didn’t allow her to trample all over your boundaries is just ridiculous. Your allowed to feel comfortable in your own home. She didnt even ask first, thats how much of a power trip she is on. She is giving off some red flags. Id change the locks if I was you.
