Woman Not Inviting Sister To Party Over Behavior Towards Boyfriend Backed

A woman refusing to invite her sister to a Halloween party over her "childish behavior" is being backed online.

In a post to Reddit's Am I the A******? (AITA) forum on October 19, 34-year-old user u/Danitka said that her older sister (46) had an unexplained issue with her boyfriend (44).

Despite "nothing bad ever happening between them," the sister makes a "scene" every time the boyfriend is invited anywhere and has inexplicably banned him from her house.

Tired of her "childish" behavior, Danitka has decided to stop including her sister in get-togethers. However, the sister found out about her Halloween party plans and is now creating "drama."

Sibling rivalry—not just a childhood problem

A 2021 poll conducted by NOW TV showed that sibling rivalry can last long into adulthood. Surveying 2,000 UK adults ahead of the season three premiere of Succession, the poll revealed that 51 percent of participants had a competitive relationship with a sibling.

It found 26 percent bickered over their career, while 22 percent tried to one-up their sibling over home ownership. Another 17 percent said their sibling rivalry had manifested itself throughout their lives, with 43 percent saying their rivalry worsened on special occasions, such as Mother's Day.

Reddit users had some harsh words for Danitka's sister.

"She is probably single and jealous that OP is dating someone closer to age and she couldn't find anyone," suggested CentralAdmin.

Inner-Ad-9928 agreed, writing: "That's what I thought. She's so jello her lil sis snagged a GREAT man and he's off the market!"

Relationship expert Ken Canion said if your sibling is jealous over your new relationship, it can help to try and understand where the bitterness is coming from.

"Your sibling may feel like you are spending more time with your new partner than them, or they don't think they are good enough for you," he told Newsweek.

"Whatever the reason, it's important to talk to them about it if you want to resolve the issue."

He recommends telling your sibling how their behavior makes you feel, which can help to prevent misunderstandings and resolve the issue.

He said: "You should start by asking how they feel. If they don't want to talk about it, then gently explain that you really care about their opinion and would like to know what is going on.

"If they are still unwilling to share their feelings, it is important that you share yours."

To make sure the conversion goes well, Canion advises telling your sibling how much they mean to you, and explaining that you want to understand their concerns and move forward.

'She's 46'

In her post, Danitka said she had been with her boyfriend for nearly three years. Their relationship is a happy one and the people in her life love him—except her sister.

"Nothing bad ever happened between them and she is not able to articulate what her problem is," she wrote. "My BF is unaware of any of this."

Over the past few years, her sister has caused multiple "scenes'' when asked to spend time with Danitka's boyfriend.

"The first situation that upset me was when she made a scene when she found out that my BF would be joining us for a dinner with friends," she said.

"[The table] was initially for four as my BF didn't think he would be able to join us. In the end, he was free and I wanted to call the restaurant and change the reservation.

"At this moment she started to behave quite dramatically. After stating that the dinner was supposed to be without him, she said that she won't be coming because she doesn't want to cause the problem for the restaurant, as it is so difficult to put the fifth chair to the table LOL.

"The joke about the fifth chair still circulates well among my friends."

The second fallout was over Danitka bringing her boyfriend to her sister's birthday. After her sister invited and then uninvited her boyfriend, Danitka decided not to attend, with the sister banning the boyfriend from her house.

The poster continued: "She said 'I didn't know that you go like a package now,' after which I lost my temper.

"I explained to her that she could just say from the start that she didn't want him to come, but inviting and uninviting him like this puts ME in quite an uncomfortable situation."

After repeated episodes of similar behavior, Danitka decided to stop inviting her sister to gatherings. However, the sister somehow found out about her upcoming Halloween party—and that she's not invited.

"I've decided I won't validate her childish behavior (she's 46 by the way)," she said.

"Among my friends I am known for hosting dinners and nice parties at my place. She found out that there will be a Halloween party.

"Now there is drama, because she feels that she is being punished (and rightly so)! I told her that I didn't invite her to this party, because I have to protect her and cannot expose her to uncomfortable situations caused by my BF being present. Or existing."

Reddit users were shocked by the sister's attitude, with ComprehensiveBet1256 saying she needs to "get a grip."

"Almost choked on my cereal when I read that she's 46," said TheAshenDemon4.

"Me too," wrote Aim2bFit. "All along I had this shape in my mind of a teenager while reading. 'Til I came to the 46. What the actual hell."

Itsyoirll said: "It's her decision not to want your [boyfriend] in her home. It is your decision to not want her in your home. She got a taste of her own medicine and didn't like it."

Newsweek has reached out to u/Danitka for comment. We could not verify the details of the case.
