And just like that, the seemingly never-ending drama between Ronnie Ortiz-Magro and Jen Harley continues.

On Thursday, the "Jersey Shore" star took to his Instagram to let followers know that he's had enough of Harley's alleged "lies," but not before he called her out using screenshots of his conversation with an unknown party.

"Knows she’s crying and decides getting drunk with a sugar daddy is better," he wrote of one exchange, according to Us Weekly, while another insinuated that Harley was engaging in illegal acts.

Accompanied by a text that detailed a hookup, Ronnie asked, "Is it legal to have sexual activities for money?!? The question is.. where’s [sic] was the son? Lmaooo."

After airing out his ex's dirty laundry, the 34-year-old defended himself and his parenting of the former couple's daughter, 1-year-old Ariana Sky.

"I refuse to sit back anymore, and let a mentally unstable person ruin my name, take my daughter, try to take my freedom with lies," he explained. "I am standing up for myself & my daughter and everyone else this person has been trying to hurt over the last week. Upset because I’ve moved on with my life. I refuse to be bullied!!! I am a great father, an amazing person!"

"All I have ever done is provide for my family, and try to give a life to them I never had. I won't let a sick person used [sic] the fact that I admitted to being depressed and emotionally broken to a point I needed help," he wrote. "It wasn't because of addiction it was because being dragged by a car, beat to death with my chain before [Mike Sorrentino's] court date, having a ashtray thrown at my Face!! I am choosing to take my life back! Some people just don't want to give it back, they need that control Of abuse! Well not anymore!!!"

Ronnie ended with #LetMeMoveOn. The social media rant come a few weeks after Harley posted her own cryptic messages about their on-again, off-again relationship.

"A break from someone will either make you realize how much you truly miss/love them or how much peace you have without them," the 32-year-old shared, adding, "Nothing but Peace baby."

The MTV stars split up in October, following Ronnie's arrest for domestic violence, child endangerment, brandishing a weapon, criminal threats, false imprisonment [of Jen], and two counts of resisting arrest. He pleaded not guilty to the charges in November.
