Thomas Ravenelis accusing exKathryn Dennisof drinking and using drugs while pregnant with their son.

“The parties’ oldest child, K.C.R., has developmental and behavioral problems that have required intensive therapy. Father is informed and believes these problems are the result of [Dennis’] lack of bonding with K.C.R. during infancy. … The parties’ youngest child, S.J.R., has developmental and behavioral problems that have required intensive therapy. Father is informed and believes that these problems are the result of Mother’s drug and alcohol consumption while S.J.R. was in utero,” the documents state.

Dennis’ attorney had no comment.

In a statement, Ravenel’s attorney told PEOPLE they “cannot comment as to the substantive matters of this litigation. However, in regards to the remarks that my client’s allegations are ‘defamatory,’ such allegations do not constitute defamation if they are, in fact, true. Such truth will reveal itself, properly, and in due time, before a court of law.”

Dennis, 26, previously lost custody of the kids and entered rehab in 2016 after she tested positive for marijuana and failed a drug test.

In 2016, Ravenel was awarded full custody, but Dennis has sinceearned back 50/50 custody. Explaining what it felt like to no longer be with her children all the time,Dennis told PEOPLEin May 2018, “when you don’t have your children with you and they’re at such fragile, young ages, it just feels like part of you is not there.”

In October, shefiled documentsin Charleston seeking to obtain primary custody of the two children, and on Nov. 6, Ravenel filed a counterclaim, vehemently denying all of Dennis’ allegations.

“Father is informed and believes that Mother’s suit for a change in custody was not brought out of concern for the best interests of the minor children,” the documents state.

Since Ravenel was awarded custody of their two children, he claims in the documents that they “have received regular, individualized therapy tailored to their developmental needs” and they “have developmentally and behaviorally progressed under his care.”

As [Dennis’] time with the children has increased under their visitation plan, Ravenel alleges that he “has observed marked regression in the minor children’s therapeutic progress,” the documents state.

According to the documents, Ravenel alleges that Dennis has purchased “synthetic urine” to pass drug tests.

“[Ravenel] is informed and believes that [Dennis] did not successfully complete her rehabilitation program, as [Dennis] tested positive for drugs after her release,” the documents read. “[Ravenel] cannot be certain that [Dennis] has maintained and sustained sobriety since the entry of the 2017 Final Order simply because [Dennis] has passed the requested drug tests since that time, as [Dennis] has a history of purchasing synthetic urine for purposes of passing drug tests.”

He further claims that producers onSouthern Charmhave sold drugs to Dennis.

“[Dennis] buys, sells, and trades prescription medications to and from friends, cast members, and show producers to support her prescription drug habit,” the documents read.

Bravo did not respond to PEOPLE’s request for comment.

He claims that Dennis “becomes overwhelmed after having sole care of the minor children for more than a few days, causing [Dennis] to further engage in illegal drug use and/or prescription drug abuse as a coping mechanism for anxiety and stress” and 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, kleptomania, self-mutilation, and Cluster B Personality Traits, including histrionic and borderline personality disorders.”

The court documents also allege that this past fall, Dennis committed a hit-and-run “on or about October 29, 2018.”

“[Ravenel] is informed and believes that [Dennis’] failure to immediately inform the injured party as to the damage she inflicted on the party’s vehicle reflects a gross lack of character and integrity, causing Father concern as to Mother’s ability to be a moral example and role model for the minor children,” the documents state.

Additionally, he is asking that Haymaker Media Inc. and/or Bravo Media Productions, LLC be prevented from “disseminating and/or airing any Season 6 and/or otherwise unaired video footage which features the minor children in this matter and/or which directly or indirectly concerns the minor children, this litigation, and/or the ongoing custody dispute between [Dennis] and the Third Party Plaintiff,” the documents state.
