We all know that moment when a risky relationship experiment backfires spectacularly. For one 24-year-old, accepting a bizarre invitation from her best friend turned into a tangled web of accidental romance and shattered boundaries. She thought she was just being a supportive third partner to her best friend, Amy, and Amy’s boyfriend, Rick. Instead, she accidentally exposed a toxic dynamic that had been brewing between the couple for years.

When Amy decided she suddenly wanted to close their polyamorous relationship back up, the emotional fallout left everyone reeling, and lines were crossed that could never be uncrossed. Curious how it all unfolded? The full story is right below.

She Forced Her Boyfriend to Try Polyamory, Now He's Leaving Her for the Friend She Invited

AITAH for causing my best friend and her boyfriend to break up?

The stage was set for a classic third-wheel disaster, though the original poster had absolutely no idea she was stepping into a trap.

So my (24f) friend, I'll call her Amy (24f), was dating her boyfriend, I'll call him Rick (24m), for 2 years. About 6 months into it, she tried to convince...

Amy’s grand plan to open the relationship inadvertently handed her boyfriend the exact emotional baseline he needed to realize his own worth.

The quickest way to ruin a relationship isn’t by inviting a third person into it—it’s by using that third person to fix what was already broken. In the non-monogamy community, Amy and Rick’s situation is a textbook example of a phenomenon known as unicorn hunting—though with a twist. Usually, this term refers to an established couple seeking a third partner to fulfill their own specific needs without regard for the newcomer.

According to relationship psychology experts, these arrangements often implode because the original couple treats the new addition as a prop to spice up their lives, rather than a full human being with their own relationship boundaries. By forcing Rick into a dynamic he didn’t want, Amy accidentally gave him a front-row seat to what a healthy, respectful connection actually looks like. The original poster didn’t steal Rick; she simply provided a mirror that highlighted Amy’s poor treatment of her partner.

If you ever find yourself navigating a newly opened relationship, start by establishing clear communication protocols. Ensure all parties have equal say in boundary-setting before making any commitments, and regularly check in to confirm everyone feels valued.

Community Opinions

Reddit came in hot and nearly unanimous, crowning the original poster blameless while roasting her former best friend for playing games.

u/URPLE_Eebra Nta. How can you be a homewrecker if this was Amy's idea. Seems like Amy would be the one who "wrecked home" no? It's her idea. Her choice. Rick...

u/PetrogradSwe NTA Amy played games and got a result she didn't want, so she wanted to change the rules. You and Rick sound much more compatible than Amy and Rick...

u/Bear_Caulk This whole situation is hilariously stupid and why any of you thought this would work is beyond me.

u/Adorable_Claim_2984 NTA. Your friend that pushed her boyfriend into something he didn't really want to begin with is an AH. You didn't cause their breakup, the friend did by treating...

u/Terra-Perspective You are not the AH. Polyamory is complicated and she ended up losing. Sounds like you treat Rick with respect and you both deserve happiness.

u/AuntAda You didn't cause the breakup. Amy did this to herself from beginning to end.

u/2cents0fucks NTA. Amy caused her own breakup by pushing Rick to do something he didn't want to do, was not comfortable with, and by treating him badly. He realized he...

u/QuickSquirrelchaser How dare you show him that a partner can show human kindness and not treat him like an atm. Obviously NTA.

u/capitol_thought Stay away from this toxic mess. You should have never gotten involved in the first place so distance yourself from both of them and seek some real friends!

u/Infinite-Employee314 NTA but I do think you should have turned down her offer to avoid any messy situations like this and Amy should have never asked a close friend. She...

A few commenters also pointed out that the mutual friends calling her a “homewrecker” seriously need to reevaluate their definition of the word.

This bizarre love triangle proves that you can’t control other people’s feelings, especially when you’re the one who changed the rules of engagement. Amy took a massive gamble with her relationship and lost, while Rick found the respect he’d been missing all along.

Do you think Amy was secretly trying to find a way to date other people, or did she genuinely underestimate how polyamory works? And if you were in the original poster’s shoes, would you date your ex-best friend’s ex-boyfriend?
