Fury As Man Confesses Love to Girlfriend's Teen Sister Then Lies To Family

A man has ignited a major family feud after apparently confessing his love for his girlfriend's 17-year-old younger sister.

The man's alleged actions were detailed in a thread posted to Reddit by the teen sibling who shared the story to social media under the handle throwawaysosacc. It has since earned over 9,600 upvotes thanks, in part, to the dramatic fallout that followed his confession.

It's a fallout that has left the two sisters estranged from one another with other family members taking sides in an argument that shows no sign of being rectified.

According to a study conducted by De Montfort University and Ulster University, people who grow up with a sister are more likely to be happier than those that do not. Over 570 people aged between 17 and 25 were polled as part of the study, with researchers asking a series of psychological questions that touch upon topics including mental health.

What they found, time and time again, was that those who had sisters growing up were encouraged to open up more about their feelings which, in turn, gave them a more optimistic outlook on life.

This enhanced communication was key to boosting overall psychological health.

Yet, for the teen posting to Reddit, communication proved to be her undoing. When her older sister's boyfriend, J, first told her he had "feelings" for her and loved her "more" than her sibling, she was quick to reject him, and let him know she would be telling her sister what he had said.

"He begged me not to tell my sister because he still wanted to date her and I told him that he can't date someone if he doesn't have feelings for them," she wrote.

However, even after confronting her with what happened, her sister was quick to side with J after he told her "a whole other story" by J about her coming on to him.

"She told me that she's always known that I was jealous of her relationship with J and that she couldn't believe I'd go as far as lying about J confessing to me," the teen wrote.

Though the teen "tried to defend" herself but her mom soon sided with the older sister and her boyfriend with several of her aunts following suit. Only her dad listened to her side of the story.

The issue has rumbled on, with her sister accusing her of being "obsessed and jealous" of her relationship. "It feels so horrible to be accused of such a thing," she wrote.

While things may be rocky at home for the teen, she found plenty of support on social media. Nerdyiaxx said: "She'll find out about J someday and she will remember that you warned her and regret how she treated you," with Blade_982 commenting: "Your mum's behavior is appalling. Your sister is blinded by infatuation. Your mother has no excuse."

Elsewhere, im_nue suggested: "record every interaction you have with J so at least you can have any proof" but GlobalLeader advised against that, writing: "don't talk with J or send any message because he will use it against you... I hope the truth comes out soon."

Emily Simonian, a Licensed Marriage and Family Therapist who is Head of Clinical Learning at Thriveworks, told Newsweek was a "tough situation" for the teenager to face and she needed to "think about what she needs from her family right now" rather than focusing on the bigger issues involving the boyfriend.

"She might start by sharing her feelings in a way that doesn't point blame at her family members; something like, 'I feel so sad and alone right now', rather than, 'I'm so upset with you and I can't believe you think I'm lying,'" she said. "Sharing her experience and softer emotions is likely to help her family members feel more compassionately."

She also encouraged the teen to find a "trusted confidante" like her dad or, alternatively, a school guidance counselor or therapist who is "open to listening and talking" things through.

"Instead of being angry, upset, and cutting off communication with her, could her mom and sister consider her motives and view it as a cry for help?" she added.

Newsweek contacted throwawaysosacc, but could not verify the details of the case.
