The pair’s relationship has been filled withup and downssince welcoming their daughter in April 2018. And as fans recall, they have awell-documented historyof alleged abuse on both sides.

In July, it was confirmed thatHarley would not be facing domestic battery chargesafter she allegedly threw an ashtray at Ortiz-Magro during a New Year’s Eve party. The Clark County District Attorney’s Office confirmed to PEOPLE that Harley’s case had been dismissed.

TheJersey Shorestarfiled a police reportin January against Harley after the two allegedly got into a heated argument at the Las Vegas strip club Hustler.

“She was mad about something she saw on his phone [and] she freaked out,” a source previously told PEOPLE, saying she allegedly “lunged” at Ortiz-Magro, and “took an ashtray from the table and threw it at his head, busting his nose and lip.”

Days later, the reality star shared photos on social media that revealedfacial injuries, including cuts on his nose.

Harley was arrested in May on suspicion of domestic battery and her bail was set at $3,000. Her arrest came after she called the police, saying that someone had a gun. When authorities responded, they found that Harley had anoutstanding warrantfrom the New Year’s Eve incident, TMZ reported at the time.

“Ariana is currently with Ron’s family members while he’s traveling for a work commitment,” a source close to the coupletold PEOPLEafter Harley’s arrest. “Ron’s number one priority is his daughter. Not Jen. He’s always going to make sure Ariana’s needs are put first. He’s continuing to make all the necessary steps to make sure she is well taken care of.”

The following month, Harley shared a sweetFather’s Day tributeto Ortiz-Magro, calling him “the best father.”

“We couldn’t ask for a better dad than you!” she continued. “Thank you for being the best father to our daughter we love you.”
