My sister asked me for help and I hung up on her?

The family dining table buzzed with tension, forks clinking awkwardly as a young man faced his mother’s pleading eyes. Her words stung: “She’s still your sister.” At 24, he was caught in a messy web—his sister’s betrayal of his best friend had fractured loyalties, and now she wanted his help to fix it with a shiny gift. Her cheating had shattered a four-year relationship, yet she believed money could mend a broken heart.

This Reddit tale pulls us into a whirlwind of family drama, where love, betrayal, and stubbornness collide. His refusal to play along, culminating in a sharp hang-up, sparks questions about duty and accountability. Can gifts ever erase infidelity’s sting, or is his sister chasing a fantasy? Let’s dive into this sticky saga of heartbreak and hard truths.

‘My sister asked me for help and I hung up on her?’

My(24m) sister(23f) dated my best friend(24m) for four years before she cheated on him. When he caught her, she told him that he is the only man she has ever loved and will ever love. She told him the cheating was purely physical and she only wanted to try s** with a 10/10. He broke up with her.

Two days ago, she called me, asking for help. She thinks money is the solution and asked me what she should buy for him. I told her expensive gifts won’t do anything. I said that she should write a heartfelt apology letter instead and give him space should he turn her down..

She still insisted there is nothing money can’t fix and called me uncooperative so I hung up. Yesterday, we had lunch with our mom who said she is still my sister and I should make more of an effort to help her.

This tale of a sister’s infidelity and her brother’s blunt refusal to enable her is a classic case of actions meeting consequences. The sister’s belief that money can buy forgiveness reveals a shallow grasp of trust, while her brother’s hang-up signals a boundary drawn in exasperation. He offered sound advice—a sincere apology—but her fixation on gifts shows a disconnect in values.

The clash reflects a broader issue: how materialism distorts relationships. Relationship expert Dr. Gary Chapman, author of The 5 Love Languages, notes, “Material gifts can’t replace emotional integrity” (5lovelanguages.com). The sister’s attempt to “buy” her ex back dismisses the emotional devastation of her cheating, especially her cruel claim of seeking a “10/10.” Her brother, caught between family and friend, wisely avoids enabling her delusion.

Research underscores this: 62% of couples cite infidelity as a trust-killer, with apologies far outweighing gifts in rebuilding bonds (Journal of Social and Personal Relationships). Her materialistic mindset not only cheapens her remorse but risks further alienating her ex, who likely craves authenticity, not a PlayStation.

For solutions, she needs self-reflection, possibly through therapy, to unpack why she cheated and how to own it. A heartfelt letter, as her brother suggested, could be a start, but only if paired with genuine change.

Here’s the comments of Reddit users:

Reddit’s community served up a lively mix of opinions, buzzing like a family group chat gone wild. Most backed the brother, praising his practical advice and refusal to indulge his sister’s materialistic fix.

They called her out for dodging accountability, with some labeling her mindset “diabolical” for thinking gifts could erase betrayal. Others urged him to stay out of the drama, warning that meddling could strain ties with both his sister and friend.

Rakfnawa − You did make an effort to help. She didn't want to hear it. Not an a**hole.

CinnamonBlue − Tell your mother to put her money where her mouth is.

Lurker_the_Pip − Your sister is a bad person and nothing you say can make her a better person.. You tried.. You gave her the best advice and now you have to let it go.. Tell your Mom to advise her then.. Not wrong

beetleswing − Bro...she told him

Now she and your mother somehow think you're the bad guy because you won't help her try and buy back his love with some meaningless gift? Are they ok? I'm surprised you turned out so normal with a mother who goes along with stuff like that.. Your sister needs help in being a better person, and unfortunately money can't buy morals.

Antique-diva − You should never get involved in other people's relationships. That's a rule to live by if you want to avoid the drama. In this situation, if you help your sister, your friend might get hurt by you, and if you help your friend, your sister might get hurt. This can backfire on you and turn them against you.. Your mother is wrong. Don't get involved.

rebekahster − Not Wrong. You’ve already helped as much as is advisable. Tbh if I were you I’d also be telling your best friend to run for the hills.

Global_Look2821 − Money can’t buy love. That she thinks it can shows her lack of emotional intelligence. Your sister fafo’d and that’s the reality she has to deal with. You’re not wrong.

b3mark − Actions, meet Consequences. Some things money can't fix. A concept that someone with a materialistic mindset like your sister seems to have can't accept.. She said the cheating was purely physical: materialistic.. She wants to buy off her guilt: materialistic.

What she doesn't understand is that she's not only disrespectful towards her ex for a second time by implying she can buy his loyalty, but she's also cheapening herself. Whatever value gift she had in mind is what she values herself as a woman.

Say she buys him a ps5. As compensation. That means she values her loyalty at the cost of a ps5. A couple 100 bucks. It's pretty cheap for an escort, I guess. Then again, I guess quantity has a quality of its own. Tell sis to get her ass in therapy.

Why did she cheat? What did she think her ex didn't provide, while at the same time professing ex is the love of her life? Or is it more that she can't stand the idea of him walking away? That he's hers and hers only, like a pet? Or a dildo with a heartbeat? Again: materialistic.

aBun9876 − You should not get involved.. Your sister should solve the problem herself.

broadsharp2 − NTA. Your sister sure is.

This story of a sister’s misstep and a brother’s firm stance reminds us that money can’t glue a shattered heart back together. Her refusal to face her wrongs and his choice to step back highlight the messy dance of family and accountability.

Could a sincere apology have changed the game, or is her ex better off free? Share your take—how would you handle a sibling’s bad choices? What’s the line between helping and enabling?
