Am I wrong for not telling my friend that I had a FWB relationship with his sister?

A man faces a tough dilemma when his best friend’s sister plans to reveal their friends-with-benefits (FWB) relationship to her sister-in-law. After both went through breakups, his regret over the situation leaves him worried about losing a lifelong friendship.

This story centers on remorse, while at the same time raising questions about honesty and responsibility in friendships. Should he come clean himself, or let someone else spill the secret? Let’s explore the details.

‘Am I wrong for not telling my friend that I had a FWB relationship with his sister?’

The story kicks off with a deep friendship and a decision made in a moment of weakness.

Things get messy when true emotions come to light.

The situation grows tense as A plans to tell someone else.

This situation poses a tricky question: How do you maintain honesty in a friendship when a mistake risks ruining it all?

This man is grappling with the fallout of starting a FWB relationship with his best friend’s sister, a choice made during a low point after breakups for both. He now regrets it, but her feelings and plan to tell her sister-in-law leave him fearing the loss of his friendship with J. Her sense of hurt suggests mismatched expectations, despite their initial FWB agreement.

Psychologist Robert Weiss, an expert on relationships, has said, “Transparency is the cornerstone of building and maintaining trust, especially when there’s a risk of emotional harm” (Psychology Today). By not telling J upfront, even unintentionally, he risks being seen as dishonest, particularly in a close friendship. Yet, A also bears responsibility for agreeing to a casual arrangement while harboring deeper feelings.

From a societal view, letting A tell her sister-in-law instead of confessing to J himself could rob him of the chance to control the narrative. If J hears it from someone else, he might feel doubly betrayed—by both his friend and sister. The advice is straightforward: he should talk to J directly, admit his mistake, and explain the context honestly. While the outcome might be tough, honesty is the only way to preserve the friendship and respect all parties.

If A wants more from the relationship, he needs to be clear about his feelings to avoid further hurt. Continuing therapy to better understand his emotions and decision-making is also key moving forward.

Here’s the feedback from the Reddit community:

The social media community chimed in with a mix of blunt advice, sharp criticism, and a touch of humor, offering varied takes on the situation.

Many users stressed that he needs to tell J himself to avoid unnecessary drama.

Some comments called the FWB choice inappropriate and questioned his intentions.

A few users took a lighter or neutral stance, suggesting the issue might not be a big deal if handled proactively.

Social media opinions largely urge him to be upfront with J to protect their friendship, though some argue his FWB choice was inappropriate from the start.

This story reminds us that honesty is key to maintaining trust in friendships. Mistakes happen, but how we handle them shapes the future of our relationships.

How should he approach telling J to minimize the damage? Is there a way to salvage this friendship, or has he crossed a line?
