In a viral Reddit post published on r/AmITheA**hole, Redditor u/throwawayaita_132 (otherwise referred to as the original poster, or OP) detailed her own struggles with having children and revealed how her prior experience influenced her emotions upon learning her sister is expecting.

Titled, “[Am I the a**hole] for my reaction when my sister told me she was pregnant?” the post has received nearly 6,500 upvotes and 4,000 comments in the last day.

“Me (27F) and my husband Will…have been married for 3 years,” OP began. “We’ve been trying for a baby for almost all that time…with no results.”

Continuing to explain that she miscarried last year, the original poster said it has been difficult to move forward but expressed gratitude for her supportive family.

The original poster also introduced her “nice and kind” older sister called Jane, but noted that Jane has never wanted children and has long prioritized her career and social life over being a mother.

That is, until recently.

“A few days ago I met up with Jane for lunch…[where] she then dropped the tidbit that she was 5 months along,” OP wrote. “I was shocked, mainly because I didn’t know she was in a serious relationship and she never mentioned pregnancy.

“She said that she slept with a guy she met at a club a couple times,” OP continued. “This sort of felt like a punch in the gut, that me and my husband have been trying for so long to have a baby and my sister…is having one whoring around.

“I thought she said she didn’t care to have kids, but Jane said that she feels ‘different’ now and this baby is a ‘blessing,’” OP added. “I got kind of tired of this, so I told her that she knows full well about mine and Will’s struggles, and she’s acting like she’s going to play happy families with some [random man’s] baby.”

Discussions about having children and other pregnancy-related topics can be challenging for many and require a great deal of sensitivity and thoughtfulness from everybody involved.

Over the last decade, numerous parenting and lifestyle websites have published guides for how to speak with expecting mothers about their pregnancies.

These guides are usually chock full of “dos” and “don’ts” covering commonly asked questions and comments made to pregnant women and encourage readers err on the side of caution to ensure that no boundaries are crossed.

But not all conversations are that simple, especially when familial tension comes into play.

Recently, Newsweek has reported on Reddit threads detailing multiple pregnancy discussions gone wrong because of envious, insulting and insensitive family members.

In one thread, an expecting mother expressed her devastation after her brother interrupted her pregnancy announcement by lamenting that his brother-in-law was “showing off” about “knocking up” his sister and in another particularly bizarre instance, a group of siblings claimed their sister was experiencing “Schrodinger’s pregnancy” after she lied about being pregnant on numerous occasions.

In both cases—and a majority of similar ones—commenters have eviscerated family members so willing to joke or speak cruelly about pregnancy and in the case of the viral post published by the original poster, the response was largely the same.

“[You’re the a**hole],” Redditor u/StAlvis wrote in the post’s top comment, which has received nearly 28,000 upvotes. “You are being a jealous, self-centered sister. And it’s an awful look.”

“You’re acting like Jane did this to spite you,” Redditor u/Nuttonbutton added, receiving more than 3,000 upvotes. “When she says she feels unsupported, I can see why. You completely left her stranded.”

Redditor u/SuddenWhole, along with many others, shifted focus to the specific vernacular the original poster used to describe her sister’s pregnancy.

“‘Whoring around?’” they questioned, receiving more than 10,000 upvotes. “What is this, the 1950s? You’re jealous, we get it.”

“[You’re the a**hole] for…using the phrase ‘whoring around,’” Redditor u/penguin_squeak echoed, receiving nearly 7,000 upvotes.

“Your whole post sounds resentful of your sister,” Redditor u/EwokCafe chimed in. “And the added slut shaming (by referring to her ‘whoring around’) is the cherry on top.”
