Borega met Kern, whom she describes as “exceptionally handsome” and charismatic, over 25 years ago while she was working as a victim advocate at the police department. She remarked that there was an immediate connection when they first locked eyes and believed they would be lifelong partners. However, the foundation of their relationship would soon be tested by a series of betrayals that would ‘unravel’ the marriage they had built together.

In a retrospective episode of the popular podcast “Betrayal,” host Andrea Gunning revisits the unfolding of Borega and Kern’s story. It examines how their union, which included the joy of raising two children, was marred by secrets that Kern harboured. Reflecting on her motivation to share her harrowing tale, Borega revealed that a conversation with someone in a position of authority pushed her towards public disclosure. This person encouraged her to discuss her experiences, labelling them as “a great story,” prompting Borega to feel empowered to join the conversation.
The series starts by highlighting an early incident soon after their marriage in 2001. While using the family computer together, Borega stumbled upon emails between Kern and a childhood friend, discussing what might have transpired had they rekindled their past relationship. Kern’s teary apology and suggestion of couples therapy following Borega’s confrontation marked the initial signs of deeper troubles within their marriage.
A turning point arrived in April 2022, when Borega received a text that would change her life forever. The message read, “I’ve f—ed up the worst I’ve ever f—ed up in my life. You’re going to want to divorce me.” This was the beginning of revelations regarding Kern’s misconduct as a police officer. He confessed to receiving oral sex in his cruiser and lying during an internal investigation as a result. Borega later discovered this was not the first time Kern had faced scrutiny over his behaviour, having previously been accused of sexual harassment in 2019 when serving as the interim public information officer.
Further compounding the revelations, a man confronted Kern at their home, accusing him of having an affair with his wife, bringing to light allegations of sexual encounters outside his marriage. Audio recordings from interviews with the woman’s claims shed light on Kern’s prior indiscretions, insinuating a troubling pattern of behaviour during his time as a police officer.
Borega watched as the investigation unfolded, with Kern initially denying the allegations before later admitting to sexual encounters with multiple women. As the crisis escalated, he was advised by a psychiatrist to enter a rehabilitation programme for first responders suffering from PTSD. Borega received alarming feedback about her husband’s struggles from his case manager, who warned her of the severity of Kern’s issues and implied that she would be better off leaving him.
Amid these challenges, Borega and her children faced additional heartache from Kern’s infidelity. Kern allegedly had an affair with the mother of a child who had bullied their daughter, an act which further shattered the family dynamic. Borega recounted the painful moment when Kern confessed to the affair on her birthday, which served as a blatant affront to their family.
Their children, notably Borega’s son, reacted strongly to the news of their father’s actions, ultimately deciding to cut ties with him entirely. Despite his absence, Borega has found solace in her family’s resilience, often recalling how her son found comfort in Bob Marley’s “Three Little Birds,” symbolising hope amidst turmoil.
Since sharing her story, Borega has received numerous messages from women experiencing similar situations. She stated that revealing her most traumatic experiences has been a challenging but ultimately therapeutic process, allowing her to feel validated in her journey of healing.
“Betrayal: Dirty Secrets” offers audiences a raw account of Borega’s tumultuous relationship and an exploration of personal strength in the face of betrayal. All three episodes of the docuseries can be streamed on Hulu, providing insight into a story of resilience and the often harsh realities of trust and fidelity.
