"I think my husband might be having an affair," wrote Davina Kruger in a post to a Sydney Facebook group for mums.
"We've been married for 5 years now," she continued, "and have two beautiful children together."
Ms Kruger shared that while her marriage started well, it wasn't long before she began noticing a difference in her husband's behaviour.
"He started going out a bit," she wrote, "usually in the middle of the day."
And, despite saying he'd only be gone for half an hour, Ms Kruger explained that more often than not " 2 to 3 hours would pass before he would come home looking exhausted and not wanting lunch."
Reflecting on the changes in her marriage, Ms Kruger noted that the "periods of absence" seemed to coincide with the stress of renovating their house.
Feeling increasingly paranoid, Ms Kruger admitted that she started going through her husband's bank statements, searching for clues – "giveaways" –amongst his spending.
And yet, instead of flowers she didn't receive or strange hotel bills – what Ms Kruger found left her completely perplexed.
"The only things I found were expenditure on nails, tool kits, shovels, plants, soil, tools, brushes etc.," she wrote.
"Who is this Bunnings?" Ms Kruger asked the group, of the mysterious mistress. "And what are you doing with my husband every weekend?"
The frustrated mum's hilarious post has resonated with other women - many recounting their own experience of their partner's "affair" with Bunnings.
"I could smell it on my husband when he comes home! Very distinct smell of sausage sizzle," one mum commiserated.
"My husband has also been seeing Madame Bunnings for some time," shared another.
Ms Kruger told Essential Kids that she wrote the cheeky post when she was feeling bored on a Saturday night – her kids tucked up in bed, her husband watching recordings of MacGyver.
"It occurred to me how often my husband sneaks off to Bunnings, usually on weekends, but also the occasional weeknight," she said.
"I was wondering if I was the only wife out there that was suffering from having a disappearing husband."
Judging from the response her words received, however, it's clear Ms Kruger certainly isn't alone.
"I was shocked to discover that hundreds of women were in the same boat as me," she said. "Madame Bunnings was working her magic. It was a phenomenon that I don't think I fully understood."
Perhaps, Ms Kruger suggested, "It dates back to the days when men were hunters and gatherers."
The mum added that Bunnings isn't the only mistress her fellow mothers were lamenting.
"Wives and partners also complained about similar mistresses called Supercheap Auto," she said, as well as cricket and football.
