Should I Ban My Brother's Girlfriend From My Wedding? | AITA
AITAH for telling my brother his girlfriend can't come to my wedding due to her outrageous behavior?
Some families have wedding drama, and then there’s the kind that starts with “squeezing your stomach” and ends with shattered glass. In this Reddit post, OP is one week away from her wedding when her brother’s girlfriend, Kaylee, decides she has some very specific opinions about her fiancé’s body.
OP says she and her brother have always been close, and her fiancé and brother get along too. But Kaylee’s first visit to meet the family went badly, with rude comments to OP’s mom and general disrespect. Fast forward to a pre-wedding drinks hangout at OP’s place, and Kaylee escalates from obnoxious to unhinged in minutes.
Now OP is stuck asking whether Kaylee can still be part of the wedding after the phone-shattering incident and the full-body chaos that followed.
Original Post
I'm not sure if I'm posting in the correct spot; I barely use Reddit, and when I do, it's just for cooking recipes. So, I (24F) have a really good relationship with my brother (27M).
My soon-to-be husband (25M) and he also have a good relationship. About four months ago, my brother met this girl (I'll call her Kaylee), and about a week after they began dating, he brought her over to introduce her to the family. It went horribly. She had no manners, no respect; during her first meeting with our parents, she told my mother that maybe she should "cut down on the food" and generally kept disrespecting and shaming my parents for anything at all.
My fiancé and I are getting married next week. Invitations have been sent out, including to my brother and his girlfriend.
Yesterday, though, she and he came over because we were going to go out for drinks. My husband is a little chubby in his stomach, but he has the kind of body where it's mostly muscle with just a little fat, so he's nowhere near obese.
Kaylee randomly starts squeezing his stomach and saying, "Aw, aren't you a little chunky?" What the f**k?? So naturally, I'm just like, "Don't touch my fiancé; you have your own tubby man to squeeze on; stay off mine!"
And she starts getting mad, saying, "Well, my boyfriend isn't nearly as chunky, so it's just more fun to squeeze on fatter people's stomachs. Us skinny girls have to have some fat to squeeze; if not our own." Okay..........?
What!!!! So now I'm just even more confused.
Somehow it escalates, and I don't exactly remember what led to this, but she threw my phone into a glass table and shattered it. My mother had given that table to me weeks prior, and I loved it.
She started slamming our stuff around and screaming in tongues; you couldn't even understand her. My brother had to pull her out of the house, and she's clawing at him while I just stand there like, "What the F**K just happened????"
My fiancé tells me he doesn't want her at the wedding, which obviously I wouldn't either. We text him that we do not want her attending; if he comes, she CANNOT come.
He is livid. He's saying, "She has mental issues; she sometimes breaks out like this," and whatever other nonsense.
I tell him, "Her mental status is not our problem, and I definitely do not want that insanity on my important day." He's telling me I'm selfish and that I need to show some respect because it seems like I don't support mental health. My fiancé literally had two years of major depression, and I stuck by him through his outbursts, but never once did he break things and claw at me.
He and Kaylee are then both completely blowing up my phone with angry messages that she didn't do anything wrong and that she can't control herself, which really isn't my fault. Truthfully, if she can't control herself, I don't want an animal attending my wedding with the risk of another outburst like that. I blocked both of them just for the time being until I can really figure out what to do.
Now, my fiancé is with me on this, but nobody else is. I just wonder if maybe I reacted wrongly or if I'm seeing something that really isn't as out of proportion as I thought it was.
I guess I just need perspectives from other points of view. Sorry if this is all over the place.
I'm stressed.
The unfolding drama surrounding the bride-to-be and her brother's girlfriend highlights a common phenomenon in family dynamics, particularly during significant events like weddings. These occasions often act as a magnifying glass, exposing simmering tensions and unresolved issues that might otherwise remain hidden.
In this case, the original poster's discomfort with her brother's girlfriend illustrates how one person's exclusion can lead to broader familial discord. The stakes are high, as relationships could become strained not just between the bride and her brother, but potentially ripple through the entire family unit.
This situation serves as a reminder that major life events can amplify existing conflicts, making it crucial for individuals to navigate these emotional waters carefully.

The first red flag was Kaylee’s “cut down on the food” comment to OP’s mom, and it only got worse from there.
Studies show that behaviors perceived as outrageous or inappropriate at family gatherings can trigger strong emotional responses.
Understanding the motivations behind such behaviors is essential for resolving conflicts.

During drinks at OP’s house, Kaylee starts grabbing OP’s fiancé’s stomach and calling him “chunky,” like that’s a normal thing to do.
To address the situation effectively, it's important to express feelings calmly while maintaining respect for others.

Emotional responses during family events can significantly shape interactions and relationships.
Understanding these dynamics is essential for improving family interactions during significant gatherings.

When OP tells her to stop and Kaylee doubles down about “fat to squeeze,” the argument turns physical way too fast.
Families should work towards creating an environment where all members feel valued and respected.
Regular family check-ins can also help to maintain positive relationships over time.
