Family drama can become intensified when family lives with you.

In today’s story, a sister moves into her brother’s guest house, and now the brother’s girlfriend is furious.

Let’s see how the story plays out…

AITA for not asking my GF if my sister can live with us.

I Jeff (28m) have a younger sister Julia (27f). We are orphans and spent our lives in orphanages, and this might be the reason my sister clearly has some mental health problems. (Not diagnosed, she has never made the first step – admitting any problems)

At first, she seems like a normal person, but she can’t keep anything or anyone in her life longer than a few months or sometimes a year. She changes jobs and friends more than some people change socks, and it is always someone else’s fault when things don’t work out.

All her coworkers and bosses are always a**h**** every time something goes south.

OP built a guest house to give his sister a place to stay.

I am used to her nonsense and can keep our relationship working as I know her well and I have my own set of rules – for example, I never lend her money.

It might be narcissism (I am no psychologist though) and I am the “flying monkey”, but a self-aware one giving her only things to keep her from ending up in the street.

Years ago I built a “guesthouse” on top of the garage which is a separate building in my yard, so I could offer her a place to stay every time she got kicked out because the landlord was bad or she just lost her job and can’t afford it anymore – in short I provide her warm place to stay, bed to sleep in and keep food in the “guesthouse” fridge until she gets on her feet again. It is basically like a studio apartment.

OP told his girlfriend about his sister.

I met my girlfriend Lenna (26f) a year ago, and I told her about my relationship with my sister, and she did not make much of it.

It is like she did not really listen to what I told her or what she expected, that person who is over 25 must be grown up by now.

Moving on to the problem:

His girlfriend doesn’t want his sister living in the guest house.

My sister made a record and worked in one place for more than a year straight! And of course, things went south this summer and she can’t afford rent and she is back in my “guesthouse”.

That infuriated my girlfriend, that I did not even ask her “I thought this is our home!”

And that she sets bad example to our kids (We both have a kid from previous marriage)

His girlfriend is mad at him.

I tried to remind her, that I told her what relationship I have with my sister. She is the only living relative I have (besides my kid).

I pointed out, that it would be stupid to ask her opinion on something I told her before might happen anyway.

Now she calls me an a**h*** for acting like it is not her home, for not asking if she is okay with someone else staying in our home. (Technically on our land, separate building.)

AITA?

It sounds like the girlfriend is the one in the wrong considering OP warned her about his sister.

Let’s see how Reddit reacted…

This reader thinks OP should’ve told his girlfriend.

Another reader thinks OP did warn his girlfriend.

This person thinks warning the girlfriend wasn’t enough.

Another reader called OP an “enabler.”

This reader agrees that OP is an enabler.

I wonder if he could help his sister get therapy, perhaps make it a requirement in order for her to live with him.
