AITAH For Exposing My Partner’s Cheating To Their Family

I never imagined I’d be that person – the one airing dirty laundry on Reddit. But here I am, sleepless for the third night, wondering if I crossed a line when I told my partner’s entire family about their affair. Part of me feels justified. The other part? Well, let’s just say Thanksgiving dinners are going to be awkward forever.

The Discovery Phase

It started with little things. Late work nights that didn’t match pay stubs. Perfume that wasn’t mine. That sixth sense you get when someone’s body language changes. I’ll spare you the cliché detective story – we all know how it goes. The confirmation came via a notification that popped up on our shared iPad while I was making coffee: “Can’t wait for round 2 tonight 😈”

Confrontation Gone Wrong

When I confronted them, I expected denial. Maybe tears. Definitely lies. What I didn’t expect? The shrug. The “we should see other people” like they were suggesting we try a new pizza place. Three years together, and my pain warranted less emotion than choosing a Netflix show. That’s when something in me snapped.

The Family Dinner

Here’s where I might be the AH. Their parents invited me for Sunday dinner two days later – completely unaware of our implosion. Normally, I’d make an excuse. But sitting across from their mom gushing about “when you two give me grandbabies,” while knowing their child was balls-deep in a coworker? Nope. I calmly said, “Actually, [Partner] is dating Jessica from accounting now. Ask them about the hotel receipts.”

The Aftermath Explosion

Cue the theatrics. Their dad stormed out. Mom started crying. Sister texted me later saying I “ruined everything.” Meanwhile, my (ex)partner blew up my phone with threats to sue for defamation – until I forwarded the screenshots to their entire contact list. Petty? Maybe. But watching them scramble to explain why they’d been banging their assistant was delicious revenge.

Was It Justified?

Here’s my moral dilemma: Their family adored me. We had real relationships separate from my partner. Didn’t they deserve to know why I’d suddenly vanish? Or was I just weaponizing their affection to inflict maximum damage? I keep replaying their mom’s devastated face – not at the cheating, but at how she found out.

Reddit’s Brutal Verdict

I posted this on AITAH first. The comments were savage. Top responses: “ESH but you’re my hero” and “This belongs on NuclearRevenge.” Surprisingly, several therapists chimed in saying public humiliation rarely leads to genuine accountability. One pointed out that I’d now made myself the villain in their family’s narrative. Ouch.

Where I Land Now

Two months later, the dust has settled. Their family did apologize after verifying the truth (turns out assistant Jessica was married too – plot twist!). My ex is reportedly “taking time to reflect” (read: hiding from relatives). As for me? I don’t regret exposing the truth, but I wish I’d done it with more dignity. Lesson learned: cheaters deserve consequences, but nuclear options leave fallout for everyone.

So tell me honestly – was I the AH for burning down their family relationships along with our romance? Would you have done the same? Sound off in the comments (but be gentle, I’m still healing).
