It’s one thing to have family stay over for a few weeks. It’s another to live under the same roof with someone who treats every conversation like a competition. Sarcasm, jealousy, and pointed remarks can poison even the closest bonds.
That’s the situation one woman found herself in when her brother and sister-in-law moved into her pool house. After weeks of biting comments about her appearance and lifestyle, her sister-in-law went too far, mocking her in front of everyone.
The blowup that followed left the family divided, and now she’s left asking the internet if she did the right thing.
This situation presents a strong conflict between hospitality and respect.
On one hand, the OP had welcomed them to stay, offered resources and space, and arguably had a right to expect respectful behaviour.
The SIL’s comments, especially in front of children, can reasonably be viewed as disrespectful and dismissive, even provocative, of the OP’s values and identity.
On the other hand, the brother and SIL were guests, with kids, presumably trusting the OP’s family for shelter during a remodel.
There is an expectation of care and support in family settings; the abrupt eviction could feel harsh, particularly to the children.
In essence, the OP is protecting boundaries vs. the guests expecting hospitality and grace.
Zooming out, this touches on broader themes of sibling/family dynamics and the interplay of power, wealth, respect and identity.
Research shows that persistent insult-laden relationships among siblings, or in-laws, can degrade mental health and family ties. For example, sibling bullying has been linked to lower self-esteem and life satisfaction in young adults.
Also, when one sibling perceives the other as “toxic” (insults, belittlement, habitually disrespectful) professionals say it may be time to reassess the relationship rather than simply tolerate repeated harm.
In this particular story the SIL’s repeated public barbs at the OP’s lifestyle and identity appear to have crossed what many regard as acceptable sibling/in-law behaviour.
Clinical psychologist Yasmine Saad told Newsweek: “For a sibling to be labeled ‘toxic’ there needs to be a regular pattern of negative, detrimental behaviors… like belittling your children or your job, or constantly making you feel undermined.”
In the OP’s case, the SIL’s remarks (“only working mommies know how hard it is…”, bikini top comment) seem to reflect those patterns of undermining.
Saad’s insight helps clarify why the OP likely reached a breaking point, it wasn’t a single remark alone, but a series of belittling statements that eroded the OP’s ability to feel safe and respected in that shared space.
What might the OP do going forward? She can start by acknowledging the emotional rupture, she might say to her brother and SIL something like, “I’m sorry we had to ask you to leave so abruptly. Your presence is valued but the constant commentary felt hurtful, especially in front of my children.”
She can propose laying down clear boundaries for any future stays: e.g., respectful language only, no commentary about parenting, clothes, or lifestyle; advance warning, agreed sleeping / occupancy arrangements for shared space; and a timeframe.
She might offer a mediated conversation with all parties (perhaps with a neutral family counselor) to untangle hurt feelings.
Importantly, she can decide whether continued stays are feasible OR whether a less-intimate guest role (maybe short visits but not full stay-over) is more sustainable for her peace of mind.

This batch of commenters roasted the sister-in-law for her “delusional victim act.”

Not everyone was convinced the story was 100% real.
These commenters went for humor, turning the thread into a mini comedy show.

Family drama can get ugly fast when pride and disrespect collide. Kicking out a sibling’s family isn’t a light choice, yet sometimes protecting your peace outweighs keeping the peace.
Do you think the OP overreacted to one cruel remark, or was it long overdue after endless digs from her sister-in-law? If you were in her place, would you have drawn the line sooner or let it slide?
