'My success as a celebrity bothered him': RHONY star Ramona Singer reveals why her marriage to Mario ended

She filed for divorce for the second time from estranged husband Mario in August 2014, ending 22 years of marriage.

And now, Ramona Singer is revealing what led to the separation - including his August 2014 cheating scandal.

'My success as a celebrity bothered him,' the 58-year-old told People about her failed romance while promoting her new memoir, Life On The Ramona Coaster.

'I think he felt that we were no longer a team,' she said. 'It was my success as a celebrity reality star and notoriety that bothered him.' 

Ramona is one of the original members of the NY franchise, having been featured as a series regular since January 2008. 

'If someone said, "Can I take a photo with Ramona?" or interrupted our conversation at dinner, he would get upset,' she continued.

'He could have jumped in but he continued to be passive. The affair was really a symptom of unhappiness.'

The Bravo-lebrity first filed divorce papers in January after she allegedly caught Mario cheating in the Hamptons. Shortly after, the couple - who are parents to 19-year-old daughter Avery - reconciled.

But when Ramona filed for separation the second time, Mario was spotted walking arm-in-arm with another woman, sparking rumours of infidelity.

The mother-of-one took to her Twitter page to announce her single status, writing: 'I have decided to move on with my life without Mario. I tried my best to make my marriage work. I am excited for the new chapter in my life.'

The Pinot Grigio entrepreneur has documented her memorable moments and marriage struggles in her new book, Life On The Ramona Coaster, which is due out on July 28.

Although her divorce is currently in the process, Ramona remains optimistic about her love life.

'Two years from now, you’re going to see me married!' she told In Touch recently. 'I still believe in love. I was very fortunate. I was married for more than 20 years. Most marriages last 10,' she said.

'I'm on a new journey now and I have no doubt I'll find someone who will be a better fit for me today.'

As for what her next ideal husband would be like, she described: 'He's in his 50s and has been married, with children in college. He is successful but doesn’t work from 8 to 8, so we can take long weekends and vacations. And he loves to kiss!'
