Southern Charm star Dennis, 27, filed documents in Charleston, South Carolina, on Oct. 25 seeking to obtain primary custody of the two children she shares with Ravenel: daughter Kensie, 4, and son Saint, who turns 3 on Nov. 17.

In her filing, obtained by PEOPLE, Dennis accused Ravenel, 56, of relying “upon the use of full-time nannies,” referenced the sexual assault allegations brought against him and his recent arrest, and alleged he “has drunk alcohol to excess, mixed with prescription drugs, that has caused him to be impaired during periods of time in which he had custody of the children.”

Dennis accused her ex of exhibiting “periods of impulsive and uncontrollable bouts of anger” and “extreme narcissism and anger management problems.” Additionally, Dennis slammed Ravenel’s most recent girlfriend Ashley Jacobs, alleging he encouraged her to “verbally assault and attack” Dennis on the Bravo show.

On Nov. 6, Ravenel filed a counterclaim, vehemently denying all of Dennis’ allegations and accusing her of filing her complaint “in bad faith, for the purpose of garnering media attention, creating material for her storyline on Southern Charm and ensuring her marketability as a ‘reality TV star.’ ”

In his filing, obtained by PEOPLE, Ravenel alleged that Dennis’ attempt to seek primary custody was “for the sole and/or primary purpose” of securing her role on the show and “progressing her storyline as the ‘rehabilitated mother who regains possession of her minor children.’ ” (Dennis previously lost custody of the kids and entered rehab in 2016 after she failed a drug test. She has since earned back 50/50 custody.)

Additionally, Ravenel alleged that Dennis initiated her suit “with the encouragement, condonation and/or express or implied permission of the producers of Southern Charm, for the purpose of providing dramatic material for the next season.”

The counterclaim also alleges that Dennis “has been diagnosed with multiple mental health conditions, including but not limited to Bi-Polar Disorder, Obsessive Compulsive Disorder, attention deficit disorder, kelptomania, self-mutilation, and cluster B Personality Traits.” Ravenel, citing an report from a clinical psychologist citing in the documents, says he believes Dennis “is capable of being a fit parent so long as she is properly medicated and receives appropriate therapy.”

Bravo and attorneys for Dennis and Ravenel declined to comment on the allegations when reached by PEOPLE.

Ravenel is requesting that the court issue a restraint prohibiting Dennis from discussing their litigation on the show, on social media and with the press. He is also asking the court to prohibit their children from being filmed or featured on the show.

Dennis’ filing came just days before a South Carolina judge found probable cause for second-degree assault and battery charges against Ravenel in a preliminary hearing, ruling that the case will head to trial.

Police first began investigating the disgraced politician in May after a woman reported him for sexual assault. Dawn identified herself to PEOPLE as the accuser and alleged that, while his daughter was sleeping nearby, he “corralled” her into the master bedroom, dropped his pants, blocked the door and “proceeded to rip my clothes off.” Without going into further detail, Dawn said she eventually got away.

Ravenel denied Dawn’s allegations through his lawyer, as well as a separate sexual assault accusation from a woman he met on Tinder in 2015.
