Teddi Mellencamp took to Instagram on Sunday to share a defiant message amid the scandal surrounding her alleged affair with her horse trainer, claiming she has found peace with her past wrongdoings.

The former Real Housewives of Beverly Hills star, who announced her divorce from Edwin Arroyave after 13 years of marriage earlier this month, opened up about her personal journey.

‘The only person who can change your life is you,’ Mellencamp, 43, wrote alongside a video of herself working out. 

‘We have two options: pretend to be a victim or stand up and fight for yourself. We all deserve peace and happiness,’ she continued.

‘I have cried and mourned. I have taken accountability and apologized for things I have done wrong. Now, I have given myself permission to grow and thrive.’

She concluded, ‘There are three sides to every story. How can I stand up and show up for the people that do matter? This is called being an adult. This is what saying it with my full chest means.’

The former Real Housewives of Beverly Hills star, who announced her divorce from Edwin Arroyave after 13 years of marriage earlier this month, opened up about her personal journey 

On Wednesday, Arroyave, the founder and CEO of Skyline Security, 47, revealed how he avoids ‘ungratefulness and bitterness’ by making a point to appreciate the blessings in his life. 

‘If you are having trouble with finding faith, increase your graтιтude. If you are having trouble with finding graтιтude, increase your forgiveness,’ he reminded his more than 65,000 Instagram followers.

He continued: ‘Because they are inseparable, forgiveness and graтιтude will always complement each other: Forgiveness unlocks graтιтude and allows graтιтude to unleash love.’ 

Arroyave concluded his post by writing that ‘love always vibrates at the highest frequency.’ 

A day later, he returned to social media to share a the Bible verse, Psalm 71:5, which speaks about having unwavering faith and trust in God through tough times.

Within the same hour, Arroyave uploaded a shirtless gym selfie after a H๏τ yoga class, then a sweet selfie dropping off his daughter, Dove, four, to school.

Last week, his ex publicly addressed headlines about her alleged infidelity with her married horse trainer Simon Schroeder.

‘What I can say, which I’m trying very… there’s multiple sides to every story,’ the Real Housewives of Beverly Hills alum said on her podcast Two Ts in a Pod with Tamra Judge.

‘I have cried and mourned. I have taken accountability and apologized for things I have done wrong. Now, I have given myself permission to grow and thrive,’ she wrote

She concluded, ‘There are three sides to every story. How can I stand up and show up for the people that do matter? This is called being an adult. This is what saying it with my full chest means’ 

‘I’m sure everyone has seen everything all over the World Wide Web,’ she added.

Mellencamp was measured in her words when speaking on the sensitive topic, which comes two weeks after she filed for divorce from Arroyave, 47.

‘I’m not going to confirm or deny anything,’ the accountability coach said, adding cryptically that ‘there’s many people involved’ in her current situation.

Mellencamp and Arroyave are parents to three children – daughter Slate, 12, son Cruz, 10, and daughter Dove and she is stepmother to his daughter from a prior relationship, Isabella, 15.

‘I once again, say the same statement I said before – the kids, they’re the priority; for the time being that’s all I’m going to discuss on this,’ Teddi said. ‘Small kids are involved, family members – you don’t want to throw other people under the bus.

‘When it comes to kids and other people’s lives that didn’t sign up for this or did sign up for this, I got to just take a beat.’

Mellencamp, whose father is singer-songwriter John Cougar Mellencamp, 73, said she felt she needed to say something in regards to the affair issue to keep things ‘moving along’ on the podcast.

The blonde beauty said that while she isn’t ‘ready to process or talk about or involve the kids in’ certain issues centered around the split,’ she’s ‘still here,’ ‘showing up for work,’ and ‘doing the best that [she] can.’

Mellencamp and Schröeder allegedly cheated for months amid their respective marriages, and during a timeframe his wife Karli Postel had been expecting – and delivered – their second child, a source told Dailymail.com on Wednesday.

‘Karli thought it was suspicious that her husband was in Florida when she was giving birth’ in California, the insider said.

Postel eventually ‘found text messages on Simon’s phone that exposed the affair,’ the insider said, and ‘confronted Simon and Teddi about it and they confessed,’ with Teddi vowing to her ‘it would not happen again.’

Postel initially ‘didn’t tell’ Arroyave about his spouse’s extramarital affair, and ‘was willing to give Simon another chance and stayed with him,’ the insider said.

Things reached a boiling point in October when Postel ‘found proof’ that the affair was ongoing and that it had become ’emotional.’

‘Simon had a history of cheating and Karli was tired of being connected to him. Edwin only learned of the affair late last month when Karli told him.’

Mellencamp’s timing in filing for divorce at the beginning of the month was a tactical move to stay ahead of the split and control the narrative, according to the source.

‘She filed for divorce from Edwin so that he did not have the chance to file and get her for adultery,’ the source said. ‘It has been alleged that the marriage ended because Edwin cheated on Teddi, but it is actually the other way around.’

Mellencamp said that she and Arroyave had split after a 13-year marriage a day after she filed divorce documents, listing October 20 as their separation date and irreconcilable differences as the cause.

She said via a November 2 Instagram statement, ‘After a great deal of care and consideration, I have made the difficult decision to file for divorce. My priority is my children and ensuring that every care is taken with their privacy and wellbeing throughout this new chapter.’

The star added that she did not want to make ‘a public statement’ on the issue, but ‘felt being open, honest, and vulnerable is the best path forward’ to ‘protect [her] family from undue speculation and rumors.’
