Dennis, 27, filed documents in Charleston, South Carolina, on Oct. 25 seeking to obtain primary custody of the two children.

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 alleged that Ravenel encouraged on-off girlfriend Ashley Jacobs to “verbally assault and attack” her 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.”

Although the photo blasting Jacobs was deleted, it marked the first time Ravenel has posted to social media since he was arrested and charged with assault and battery in the second degree in September following allegations of sexual assault brought against him by “nanny Dawn,” who was featured on the show caring for his children. Ravenel has denied her accusations through his attorney.
