Hosting family can be enjoyable when everyone communicates, but it becomes stressful when plans are made around your home without your input.
Even small assumptions can start to feel disrespectful when they happen repeatedly.
One Redditor reached that point with her husband’s brother’s ex-wife, who still visits the family to see the mother-in-law living in their shared home.
The visits themselves were not the problem.
What bothered the poster was being informed after arrangements had already been made, including overnight stays, extra guests, and trips that seemed to assume someone else would cover the cost.
After several incidents, she finally told the woman that she was welcome to visit, but needed to ask first before making plans involving the house.
The response was far more dramatic than expected.
Scroll down to see why the poster is now wondering whether setting that boundary made her the bad guy.
A woman finally sets boundaries after a relative repeatedly makes plans involving her home without asking
A home should be one of the few places where a person does not have to wonder who is arriving, how long they are staying, or what plans have already been made on their behalf.
That is why the OP’s frustration feels so understandable.
She was not objecting to her mother-in-law having visitors or maintaining relationships.
She was reacting to a pattern in which other people repeatedly treated her household as though it were available by default.
The emotional core here is not hospitality. It is consideration.
Betty was making plans directly with the MIL, then informing the OP afterward, even though the OP co-owns the house and manages its daily functioning.
Showing up early, expecting accommodation during a plumbing emergency, arranging for an adult son to stay without asking, and assuming the MIL would cover travel expenses all reinforce the same message: everyone else’s plans come first, and the person actually running the household is expected to absorb the consequences.
There is also a useful alternative perspective. Betty may not consciously believe she is being disrespectful.
Because the MIL lives there and co-owns the property, Betty may psychologically experience the house as partly “her former family’s home” rather than as the OP’s private household.
Long-standing family roles can linger after divorce, remarriage, and changes in living arrangements.
That could explain the assumption, but it does not make the assumption reasonable.
That is exactly what the OP did. She did not ban Betty from visiting, insult her, or demand control over the MIL’s relationships.
She asked for one basic courtesy: check before making plans that involve her home.
Betty’s response, suggesting she may never visit again because the OP “doesn’t like her”, turns a practical boundary into an emotional referendum.
The OP does not need to chase that interpretation.
A realistic path forward is to keep the rule simple and consistent: visits involving the house require agreement beforehand, and the nephew can arrange his own stays directly.
If Betty chooses to treat that as rejection, that is her reaction to manage, not evidence that the boundary was wrong.
Here’s the comments of Reddit users:
These Redditors urged firm boundaries and refusing any future unannounced visits
This group joked that her threat to never visit again sounded more like a benefit than a punishment
These commenters worried the ex-SIL was taking financial advantage of the MIL and urged intervention
These users questioned why the MIL kept funding trips and spending so much time with the ex-DIL
This wasn’t really about one weekend visit. It was about someone repeatedly treating another person’s home, schedule, and finances as if permission were optional.
The poster didn’t ban anyone or create a scene; she simply asked to be included before guests or trips were arranged.
Even the nephew understood why that boundary mattered. Betty’s reaction may be emotional, but it doesn’t make the request unreasonable.
Do you think the poster handled this fairly, or should she have stayed out of plans involving her MIL?
How would you respond if relatives kept assuming access to your home?
