AITAH for Telling My Best Friend She’s Ruining Her Marriage by Oversharing on Social Media?

When it comes to friendships and boundaries, sometimes honesty can cross into territory that feels like betrayal. In today’s AITAH scenario, we’re diving into a situation where telling the truth might cost someone their closest relationship.

The Background: A Friend Who Shares Everything

A 32-year-old woman—let’s call her Mia—turned to r/AITAH with a dilemma that struck a nerve with thousands of readers.

Mia has been best friends with Lily since college. Over the years, she’s watched Lily get married, have two kids, and build what seemed like a picture-perfect life.

The problem? Lily documents everything online. From arguments with her husband to intimate details about their finances, no topic is off-limits.

At first, Mia thought it was harmless venting. But over time, Lily’s oversharing grew into a constant public airing of dirty laundry, and Mia started to feel uneasy—especially when Lily began posting about personal conflicts Mia had confided in her privately.

The Confrontation: When Enough Is Enough

A week before Mia posted her story online, Lily shared a detailed account of a fight she and her husband had over money. She included screenshots of text messages and tagged her husband’s family members, leading to a full-blown argument in real life.

Mia finally decided to speak up.

“I told her she was humiliating her husband and their marriage, and that maybe she needed to keep some things private,” Mia explained. “I said I loved her, but she was ruining her own relationship for internet attention.”

Lily didn’t take it well. She called Mia judgmental and unsupportive. They haven’t spoken since.

The Community Reacts: Tough Love or Overstepping?

Why Some Say Mia Was Right

Many commenters felt Mia was justified.

“Someone needed to say it,” one user wrote. “If your posts are causing real-world damage to your marriage, it’s time to log off.”

Others agreed that oversharing can be harmful not just to the relationship, but to children who may one day read those posts.

Why Others Think Mia Crossed the Line

Still, a few Redditors believed Mia overstepped.

“Even if you’re right, how you say it matters,” one commenter argued. “Telling someone they’re destroying their marriage is harsh, and maybe she needed empathy more than criticism.”

A handful pointed out that Mia might be projecting her own discomfort with public vulnerability onto Lily.

The Psychology of Oversharing

It’s easy to dismiss oversharing as attention-seeking, but psychologists say it’s often a coping mechanism.

Why Do People Share So Much?

• Validation: Getting likes and comments feels reassuring.

• Community Support: When friends rally around you, it feels less lonely.

• Control: Sharing the story first means you control the narrative.

But when the impulse to share overrides respect for a partner’s privacy, it can damage trust and intimacy.

Friendship and Boundaries: Finding the Line

Mia’s story is a perfect example of the fine line between honesty and judgment.

On one hand, it’s admirable to care enough about a friend to voice concern. On the other, unsolicited advice about someone’s marriage can feel intrusive—even when it comes from a place of love.

When approaching sensitive topics:

• Lead with empathy.

• Avoid absolutes (“you are ruining everything”).

• Offer support, not ultimatums.

What Should Mia Do Now?

If Mia wants to salvage her friendship, she may need to reach out and acknowledge the hurt her words caused, while also standing by her perspective.

A simple message like:

“I’m sorry for how I said what I did. I care about you and your family, and I just worry that sharing so much online could hurt you in the long run.”

…could go a long way toward repairing trust.

The Verdict: AITAH?

Most readers agreed: Mia is not the villain for expressing concern, but she might have been too blunt.

Sometimes, telling the truth means risking a friendship—but staying silent isn’t always the kinder option either.
