A man has been left red-faced after his attempt to expose his colleague for being a " cheater " spectacularly backfired - as he had completely misunderstood the situation.
The anonymous woman took to Reddit to share her story and revealed her co-worker Ken had spotted her in a bar kissing another woman and had immediately assumed she was cheating on her boyfriend, Louie.
But after taking photos of the kiss and sharing them around with their other colleagues, Ken was left embarrassed when the woman confronted him with the truth - that she's in a polyamorous relationship and that the woman, named Ruby, is as much of her partner as Louie is.
