It’s easy to take advantage of a comfortable relationship.

While it can be a good idea to give a key to your home to someone who doesn’t live there, what would you do if that person let their family stay at your place while you were out of town? Would you be okay with it, or would you kick them out at soon as you found out?

Let’s see what happens when one Redditor’s girlfriend takes advantage of her partner’s apartment.

AITAH for kicking out my gf’s sister and her kids out of my flat after my gf gave her the keys

People around me are saying I am an AH, but I need the perspective of uninvolved people.

My long-term gf has my apartment keys, as I have hers.

Only unspoken until now but [the] always-respected rule was, if you need to go to the other place, just send a text, “Hey, going to your place.”

This gesture mainly serves as a common courtesy.

Doesn’t matter if the other is at home or even responds. Just simply to tell the other you will be at their place.

I was supposed to be away 700km from home for 2 weeks for work-related stuff, but 4 days in, and our instructor got into an accident.

Work tried to find another one, but no such luck on very short notice.

That’s when a trip disruption occurred.

They decided at like 10 pm to get us the first flight home the next day at like 6 am, pay us the overtime and the next day at home, then resume our normal work schedule.

So I get home the next day at like 9am, sent a text to my gf to tell her I am back.

But, something didn’t seem right about the OP’s place…

Getting to my door, I am very confused hearing children screaming inside, since none of the people who have my keys have [loud] kids like that (my brother and my gf).

I thought I got squatters or something.

What happens next will shock you…

Opening the door, I see my gf’s sister’s kid running around after a shower, putting water everywhere. Plates of half finished ravioli on my living room ground. Their suitcases opened in the entrance.

I get inside and see the husband on my couch trying to hook up my PS2(that he must have dug out in my storage room).

[I get] into a verbal argument with him trying to understand why the heck they are here.

Well, you’ll never believe who gave them permission…

Said my gf told them they could get my flat for 2 weeks while I was gone (they wanted to visit the city for a bit, go to the beach).

My gf sent me a text while I was arguing, telling me, “Oh ok, btw my sis’ fam is at your flat”.

But that text was too little too late.

I admit, I blew up on him and the sis who left my bedroom in the meantime. Told them to leave immediately.

They argued quite a bit, my gf called her sis, then sis put up the speaker, so we could all hear, and she said I was embarrassing her, that she told them they could use my place for a while.

I threatened to call the police, also asked my brothers to come.

They left while cursing me to their children, telling that holidays are over because the mean little sister’s boyfriend cast us out.

But the repercussions haven’t been great for the OP.

I have now all of my gf’s family on my back, and even some of my own family, saying I could have stayed with my gf so the kids could have some vacations…

Also, they have read my doctor prescription papers (I put them in a specific order, and it was not the same), and obviously took some of my prescribed meds (opened a box of benzodiazepine…).

AITAH for making them leave?

We pretty much stopped talking about anything else with my gf. I feel like I am being gaslighted. I would never invite people to her apartment like that, especially without telling her.

It seems so disrespectful. Am I going insane?

So, is this partner in the wrong or did the girlfriend overstep by inviting family with no notice? Let’s read the comments below to find out.

Redditors validated the OP’s instincts.

And they advised this partner to break up with this girlfriend STAT.

They even recommended changing the locks.

And it was an overwhelming “NTA” for this tale.

This partner needs some self-respect and a new girlfriend.
