Am I Wrong for Not Letting My Sister Move Back In After Divorce?

A 28-year-old woman refused to let her divorced sister, Sarah, move back in, and now the whole family is acting like she’s the villain. The request sounds simple on paper: Sarah just split from her husband after “irreconcilable differences,” she’s crying on the phone, and she wants a place to land.

But Sarah is not exactly known for steady decisions. She moved out of the shared apartment two years ago to live with her then-boyfriend, now ex-husband, and the relationship blew up fast. The OP lives alone and says her peace matters, yet their parents are pressuring her because they cannot keep Sarah long-term.

So the question is not just whether Sarah needs help, it is whether this time will be any different.

Original Post

I (28F) have a sister, let's call her Sarah (31F), who recently went through a divorce with her husband due to irreconcilable differences. Sarah has always been impulsive and tends to make rash decisions without thinking of the consequences.

We've had a rocky relationship in the past due to her behavior that often puts me in difficult positions. For background, Sarah moved out of our shared apartment two years ago to live with her then-boyfriend, now ex-husband.

She called me a month ago, tearfully explaining that they decided to part ways and asking if she could move back in with me. I was hesitant because I know Sarah's track record of not following through on commitments and causing drama.

I currently live alone and value my independence. After a lot of consideration, I politely told Sarah that I didn't think it would be a good idea for her to move back in with me.

I explained that I need my space and that I don't want her impulsive decisions affecting my peace of mind. She was upset and accused me of being selfish and unsupportive during her tough time.

Sarah has been staying with our parents since the divorce, but they are pressuring me to let her move in with me as they can't accommodate her long-term. I feel torn between family obligations and my own mental well-being.

So, AITA?

The Weight of Family Obligations

This situation hits home for many because it illustrates the tug-of-war between familial duty and personal boundaries. The original poster (OP) is caught in a bind: she feels the instinctive pull to support her sister, Sarah, who’s just gone through a painful divorce, but she also recognizes her own limits. It's important to note that Sarah's past behavior and the emotional toll of living together could lead to resentment, making this decision even more complicated.

When family members lean on one another during tough times, it can feel like an obligation, but at what cost? The OP's hesitation raises critical questions about how much support one can realistically provide without sacrificing their own mental health.

Sarah’s call starts with tears and a big ask, but OP immediately remembers the last time Sarah “planned” her life and left chaos behind.

NTA - Your sister needs to learn responsibility. It's not your job to clean up her messes, especially after how she's treated you in the past.

YTA - Family comes first. Your sister is going through a tough time, and you should support her. She needs you now more than ever, despite your past issues.

Comment from u/MusicLover123

Sounds tough, but NTA. You have the right to set boundaries, especially considering your sister's history of impulsive decisions. Take care of yourself first.

ESH - Your sister for putting you in this situation, your parents for not finding a more sustainable solution, and you for not offering some form of support. It's a messy family dynamic all around.

When OP tells Sarah no, Sarah flips it into a character attack, calling her selfish and unsupportive during a divorce.

NAH - It's a difficult situation. Your sister is struggling, but you also have the right to prioritize your own mental health. Maybe find a compromise like helping her find a different living arrangement.

This is similar to the AITA case where OP refused to let their sibling’s friend crash on their couch.

NTA - You have valid concerns about your sister's behavior impacting your space and mental health. It's important to prioritize yourself, even in challenging family situations.

YTA - Family should stick together through thick and thin.

The pressure ramps up when the parents step in, saying they can’t house Sarah anymore, and suddenly OP’s “no” feels like it has consequences.

Comment from u/BeachLife32

NTA - Your well-being matters too. It's understandable to want to protect your independence and mental peace. Your sister needs to understand and respect your decision.

NAH - It's a tough spot to be in.

Comment from u/PizzaLover21

ESH - Your sister for involving you in her mess, your parents for pushing you, and you for not finding a more compassionate way to help your sister during a difficult time.

With Sarah hovering between her ex and her parents, OP is left wondering if letting her move in will buy relief or just restart the same drama cycle.</p>
