Aussie boyfriend’s act of revenge after discovering his girlfriend’s affair – as the professions most likely to cheat are revealed by top PI

Revenge has become its own genre, with stories of elaborate payback often going viral as people debate where justice ends and pettiness begins. 

And this week, one Australian man’s confession about getting even with an unfaithful ex left radio hosts and listeners speechless. 

Calling into 2DayFM’s Breakfast with Nath & Emma, Andre revealed he had discovered his girlfriend cheated on him shortly before they were due to attend Taylor Swift’s Eras Tour together.

Rather than let the tickets go to waste, he invited someone else. 

While most would choose a friend or relative, Andre took the nuclear option – and messaged his ex’s mother. 

Andre explained that in 2024, after the relationship ended, he stayed in contact with his former partner’s mother, having built a close relationship. 

‘My ex’s mum was of course [disappointed in her]. We talked about it,’ he said.

‘My partner and her mum wanted to go see Taylor Swift together, but [spoke to her] and said, “This is what your daughter did. Side note, do you want to go to the concert with me?”.’

As shocking as the story was, host Nath Roye asked the obvious follow-up. 

‘Did you hook up with the mum?’

Andre laughed before attempting to coyly dodge the question.

‘Let’s not air too much dirty laundry on the radio.’

For Roye, the answer was clear. 

‘Oh… [you] hooked up with the mum at Taylor Swift!’

Why does break-up revenge fascinate us?

Relationship experts have long said betrayal creates a desire to restore control. 

For some, that means blocking an ex, returning their belongings, and moving on. Others focus on self-improvement, hoping success itself will be the best revenge. 

Then there are the stories that spread online – theatrical acts of payback meant to embarrass the person who caused pain 

The appeal is obvious. Infidelity is one of the most painful breaches of trust, and stories where the wronged partner seems to win naturally attract attention. 

But professionals warn that revenge rarely brings the closure people expect and can keep emotional ties alive rather than helping someone move forward. 

Is infidelity the ultimate deal-breaker?

Andre’s story comes amid ongoing discussion about cheating and why it happens. 

Australian private investigator Cassie Crofts, who specialises in infidelity through Venus Investigations, said years of tracking unfaithful partners had taught her there is no single type of cheater.

‘Cheaters come in all shapes and sizes,’ she told the Daily Mail.

‘It tends to be more about people who have the opportunity due to their work, lifestyle or social status, a sense of entitlement or a real belief they’re too smart to get caught.’

She said people working in FIFO, healthcare, hospitality, sales and executive roles often feature in her investigations, as irregular hours, travel, and more independence can make affairs easier to hide. 

Crofts also noted that most warning signs are behavioural: changes in routine, becoming protective of a phone, using more cash, developing a new hobby unexpectedly, or blurred boundaries with others. 

Perhaps her biggest surprise after years investigating affairs is how many couples stay together. 

‘Life is complicated and not everyone is in a place to leave,’ she said.
