Redditor Asks If She's An A**hole For Making Boyfriend's Brother Sleep On The Floor After He Called Her Fat
"Bare minimum expectations for guests is that you don't make insulting jokes about your host."
A 28-year-old woman moved in with her boyfriend, and everything was fine until his brother treated her like a walking punchline. The brother did not just make comments, he made them every time he saw her, calling her “bigger” and comparing her to a St Bernard like it was a cute nickname.
Here’s where it gets messy: the OP says she’s gained weight over the past couple years, so those “jokes” hit a lot harder than he thinks they do. She tried to figure out what he even meant, asking if it was a fat joke or if he was basically implying she looked like a dog, and he played it off like he meant nothing by it.
Then the brother crossed another line, and the OP snapped in a way that has Reddit split down the middle.
The Redditor asked if she's an a**hole for making her boyfriend's brother sleep on the floor.
Reddit/ThrowRAchanceitShe explained that she and her boyfriend recently moved in together.

The OP says her boyfriend's brother has a habit of running his mouth.
The act of making derogatory comments about another's body, as seen with the boyfriend's brother, can lead to significant emotional distress. Research published in the Journal of Health Psychology indicates that weight-based discrimination can foster feelings of shame and lower self-esteem among the targets of such remarks.
These negative emotions can culminate in long-lasting psychological effects, highlighting the importance of fostering a respectful and supportive environment, especially in interpersonal relationships.
Promoting Positive Communication
Effective communication is vital in preventing misunderstandings. Emphasizing the importance of expressing feelings and needs without blame.
By focusing on feelings rather than accusations, individuals can create a more supportive dialogue. For instance, expressing how the brother's comment made her feel could lead to an open conversation and understanding, rather than conflict.
In the context of this Reddit story, the dynamics of hospitality and boundaries are crucial.
When he arrived at their place, the OP's BIL said that she is "bigger" every time he sees her, like "a St Bernard."
For context, the OP says she has put on some weight over the past couple of years.
The OP asked her BIL if that comment was meant to be a fat joke, or if he was implying that she looks like a dog.
When the boyfriend’s brother showed up and immediately went for the St Bernard comment, the OP’s patience started thinning fast.
He identifies the 'Four Horsemen' of relationship breakdown: criticism, contempt, defensiveness, and stonewalling.
When guests disregard social norms, it can create tension and disrupt the dynamics of the relationship.
Recognizing these patterns can help individuals navigate social situations more effectively.
He said he meant nothing by it, so she let it slide.
When they showed him the kitchen, he said to the OP, "I'm guessing this is your favorite room?"
At that point, she had enough and she told him he would be sleeping on the floor instead of the pullout couch.
After she questioned whether he meant a fat joke or an actual dog comparison, he waved it off like it was no big deal.
Social psychologists highlight that humor can sometimes be a double-edged sword.
Open communication is essential for addressing issues related to guest behavior.
This approach fosters a more positive social environment.
This is similar to the AITA debate over an impulsive brother adopting a puppy.
After that, he barely spoke to them for the entire weekend.
Now she's asking the Reddit community if she's the a**hole here.
Here's how people reacted.
