Woman Accused of ‘Sabotage’ After Revealing She Slept with Sister’s Boyfriend When He Claimed He Was ‘Saving’ Himself

A woman turned to the Reddit community for support following an emotional family standoff that began with what she believed was a moment of honesty.

She explained in her post that her sister was furious after learning she had once been romantically involved with the man her sister is now planning to marry.

The Reddit poster shared that she had dated her sister’s now-boyfriend briefly when they were all teenagers, a relationship she described as casual. “When I was 16 I dated my sister’s now boyfriend for about 6 months,” she wrote, adding that it “wasn’t a super serious relationship.”

She noted that despite their young age, the pair had been intimate during that time, a detail that later became the center of the conflict. “We did it a few times, but nothing obscene,” she explained, emphasizing that the relationship ended amicably and without lingering feelings.

Over the years, they remained friends, and life moved on naturally as they headed into adulthood. The poster said her sister began reconnecting with her ex years later, eventually asking if it would bother her to date him.

She reassured her sister that the past was behind her and that she had no reservations about the new relationship. “I had absolutely no problem with it and told her there were absolutely no weird feelings,” she explained, noting that the teenage romance was nearly a decade old.

The couple continued dating for three years, during which time the boyfriend sought the poster’s help in planning his proposal. She said she supported them wholeheartedly and genuinely wished them well in their future together.

The tension began during a recent dinner outing with friends, where her sister joked about wanting a proposal soon. The poster recalled her sister saying she felt like an “old maid” because the couple had been “saving themselves for marriage.”

Confused, the woman asked her sister whether she meant saving herself in this relationship or in general. According to the post, her sister responded that both she and her boyfriend “had been saving themselves their whole life.”

The woman admitted she instinctively glanced at her ex across the table, realizing the statement wasn’t true. “I gave her boyfriend a strange look from across the table and she caught it,” she wrote, explaining that her sister immediately pressed for the reason behind it.

Trying to avoid embarrassment for everyone involved, she initially brushed it off, but her sister insisted on an explanation. Feeling cornered, she told the truth: “I confessed that we had sex in high school, although it didn’t really mean anything.”

Her sister reacted with shock and anger, first directing it at her boyfriend for lying, then turning it toward her sibling when the boyfriend denied the past entirely. The poster said her sister became convinced that she was “trying to sabotage our future marriage because you’re not over him.”

The woman stressed that she had no romantic feelings for her ex and wasn’t trying to cause harm, but her sister refused to believe her. She wrote that the couple left abruptly, and the following day her sister sent a message saying she would not be invited to the wedding unless she admitted to lying.

The poster expressed regret over how the moment unfolded, wishing she had chosen different words or simply avoided the topic when questioned. She said, however, that she felt she owed her sister the truth because the boyfriend’s claim about being “saved” wasn’t accurate.

Reddit commenters quickly rallied behind her, insisting she hadn’t done anything wrong by telling the truth when pressured. One commenter wrote, “You are not responsible for facilitating his lies and you are NTA… but I doubt their relationship survives.”

Another pointed out that the sister may be choosing denial over discomfort, saying, “Hopefully, she doesn’t walk blindly into this because if he’s lied about this, he has absolutely lied about other things.”

As the situation stands, the sisters remain estranged, with friends attempting to mediate but receiving no response from the bride-to-be.
