Holly Madison and Husband Were ‘Having Trouble for Some Time’ Before Filing for Divorce: Source

Holly Madison and Pasquale Rotella‘s decision to end their nearly-five year marriage was not a shock to those who knew them.

On Tuesday, a source who knows the couple told PEOPLE that their decision to file for divorce was not unexpected.

“Holly and Pasquale had been having trouble for some time,” the source says of the former

Playboy model and the Electric Daisy Carnival founder. “This wasn’t a sudden decision.

They had a lot in common, but they were also very different people.”

Added the source: “Holly is an amazing mom and will do what’s best for her kids.

They still care about each other and will remain in each other’s lives.”

PEOPLE confirmed via multiple sources on Tuesday morning that Rotella and the 38-year-old

reality TV star had split over the summer, with another source revealing that Madison is

now based in Los Angeles and “doing okay.”

The Blast reported that Rotella, 44, filed for divorce on Aug. 31 in Las Vegas.

Rotella later confirmed the news on Instagram, sharing that he and his wife — who share daughter

Rainbow Aurora, 5, and son Forest Leonardo Antonio, 2, together — have separated as a couple.

“It is with love in our hearts and a deep respect for one another that

Holly and I have amicably made the decision to separate,” Rotella wrote in the caption

of a sweet family photo. “First and foremost, we are forever partners and parents to two

beautiful children, and are fully committed to raising them in an environment filled with love and positivity.”

He went on to speak highly about Madison, referring to her as a “talented woman” and “beautiful soul.”

“We remain the best of friends while co-parenting and continuing to support

one another in our respective passions in life,” Rotella continued.

“Though it was not a decision we made hastily or take lightly, Holly and I welcome this

next chapter in our relationship, and have every confidence that the future will bring only

the best for us and our kids. We will always be family. Thank you all for your continued love and support. ❤️”
