Thomas Ravenel and Kathryn Dennis are headed back to court in their vicious custody battle.

Despite the appearance of reconciliation between them on the reality show, the Southern Charm stars are no closer to reaching an agreement in the fight over their two children - three-year-old Kensington (Kensie) and one-year-old Saint - that has raged since last May.

Viewers who watched the Southern Charm season finale Monday night, which was filmed in December, might have anticipated a rekindling of relations was on the horizon with Ravenel and Kathryn kissing and seeming to make up.

But today, court documents obtained exclusively by DailyMail.com, lay bare the ugly truth.

Texts submitted as evidence and sent between Ravenel, here with son Saint, and Kathryn between February and March of this year belie the on screen image of them as a couple edging towards more harmonious co-parenting

Despite the appearance of reconciliation on the reality show in the season finale on Monday night, the Southern stars are no closer to reaching an agreement in the fight over their two children that has raged since last May

Texts submitted as evidence and sent between Ravenel and Kathryn between February and March of this year belie the on screen image of them as a couple edging towards more harmonious co-parenting.

In one, sent by Ravenel at 9.59 a.m. on February 6 he told the mother of his children ‘You’re wasting time and money. But keep drugging. Hopefully it will be a moot point soon.

‘The judge and guardian are shocked at your behavior. Shameful that you can’t pass a drug test.’

Several hours after Ravenel texted: ‘Keep on sexting and f***ing Ashley’s friends. It’s so sick' Kathryn decided to change her relationship status on Facebook, to ‘In a Relationship with Ashley Pillar’ - a Charleston local whom Ravenel also knows well

Hinting at concerns that Kathryn’s lifestyle may have negatively impacted on both children’s health the text continued: ‘Did you even read the audiologist’ report? All bc Kensey was under your care for two years. Hopefully I can reverse the damage. And poor Saint is suffering from what you put him through while pregnant.

‘I never want to see your face ever again.’

In later texts in the court papers Thomas tells Kathryn, ‘You have nobody to blame but that person you’re staring at when you (sic) caking on all that makeup’

He goes on to ask her ‘please no more sexy lingerie panties with a bow and a heart for a three year old please,' referring to their daughter.

And though Kathryn tells him she has ‘a huge empty and sad space’ in her heart without her children’ it is quite clear that Ravenel’s patience and sympathy has run dry.

On May 1, the day they were due to have appeared in court he texted her, ‘You are stalking people that hv been sending me messages and sending them nasty notes. I’m so done with you. See you in court. You’re mentally ill.

‘So much discussing (sic) s*** its going come out on u in court you’ll never work again or see your kids.

In court documents Kathryn claims that Ravenel ‘has had illegal substances including mushrooms and cocaine at his house while the children were under his care'

In the recent flurry of accusations and counter accusations each is now seeking to hold the other in contempt for alleged breaches in the court order that stipulated visitation guidelines for Kathryn, put in place mandatory drug tests for both and forbade either from speaking publicly about the other in a derogatory fashion

‘Keep on sexting and f***ing Ashley’s friends. It’s so sick.’

Several hours later, at 11:08 p.m., Kathryn decided to change her relationship status on Facebook, to ‘In a Relationship with Ashley Pillar’ - a Charleston local whom Ravenel also knows well.

Coming at the end of the very day she had admitted being in contempt of court, it was a demonstration of what some might interpret as contempt of a different sort - directed very squarely at the father of her children.

In the recent flurry of accusations and counter accusations each is now seeking to hold the other in contempt for alleged breaches in the court order that stipulated visitation guidelines for Kathryn, put in place mandatory drug tests for both and forbade either from speaking publicly about the other in a derogatory fashion.

Perhaps most shocking of all are allegations made by Ravenel, 54, that 24-year-old Kathryn’s drug taking, drinking and general lifestyle may have had serious consequences for both children’s health.

The former couple was last due to appear before a Charleston judge on May 1 but settled out of court with Kathryn agreeing that she was in contempt for failing to provide the court with comprehensive medical and psychiatric records including details of a 31 day stint in rehab last year.

Kathryn was previously found to have repeatedly evaded the mandatory drugs and alcohol tests, which she and Ravenel have both agreed to submit as a condition of her supervised visitation and his continued primary physical custody of three-year-old Kensington Calhoun Ravenel (Kensie) and one-year-old Saint Julien Rembert Ravenel (Saint).

Now Kathryn has accused Ravenel of ‘alienating the children’ from her. In the documents filed last month she has accused Ravenel of denying ‘court ordered visitation…since February 6.’

Worse yet, she has claimed, Ravenel ‘has allowed or encouraged the minor children to call their nanny…mother.’

Ravenel's texts to Kathryn submitted as evidence in Thomas Ravenel/Kathryn Dennis custody battle

Recent episodes of Southern Charm showed Kathryn attend Saint’s first birthday party last November hosted in a by Ravenel in a park complete with petting zoo. His invitation to her seemed to signal a softening of the combustible ex-lovers’ relations.

But the court documents paint a very different picture with Kathryn claiming that Saint’s nanny would not let her hold him at the reception for his christening on April 16. She goes on to claim that Ravenel told her that if she ‘did not leave the reception he would call the police.’

Attorneys acting on Kathyrn’s behalf have gone onto claim that Ravenel has ‘continued to disparage’ her on social media and in the media in general and ‘continued to send..harassing and disparaging texts and emails.’

More shocking are her claims that Ravenel ‘has had illegal substances including mushrooms and cocaine at his house while the children were under his care…and is abusing alcohol while taking narcotics while the children are under his care.’

Ravenel was infamously indicted for possession of cocaine with intent to supply a decade ago when he was serving South Carolina’s State Treasurer.

Friends of Ravenel insist that he is an ‘exemplary and devoted father’ yet according to Kathryn he is a man with ‘violent and abusive tendencies’ that he has exhibited to both her and their children.

She also claims that he has been ‘attempting to mislead the Court by shaving all of his body hair off prior to taking a drug test.’

Her petition to the court demands that Ravenel pay $50,000 of her legal fees, a $50,000 punitive fine and that he submit to ‘a full psychological evaluation’ based upon his ‘consistent use of opiates in conjunction with multiple instances of violent and erratic behavior.’

Two days after Kathyrn’s papers were filed Ravenel lashed back, blasting Kathryn with a claim that she has broken the court ruling banning either from speaking out against each other publicly.

The former couple was last due to appear before a Charleston judge on May 1 but settled out of court with Kathryn agreeing that she was in contempt for failing to provide the court with comprehensive medical and psychiatric records

Ravenel claims that in interviews with gossip website Realitytea Kathryn accused him of orchestrating a ‘smear campaign,’ took advantage of his inability to respond publicly to slap down any question that her drug and drink use during pregnancy adversely affected Saint and labeled him the root cause of her drug abuse in the first place.

In addition, he claims that she released partial medical records detailing drug test she had passed and failing to include ones she did not.

As well as being held in ‘criminal contempt’ his attorneys are now demanding that in light of this partial release Kathryn should now be compelled to make public all her drug tests since her release from rehab, including ‘the failed drug tests.’
