'RHOC' Divorce Turns Nastier: Gina Kirschenheiter's Ex Slams Her As 'Erratic' & 'Vindictive' Matt says his estranged wife is using the family scandal for reality TV fame.

The Real Housewives of Orange County star Gina Kirschenheiter‘s estranged husband is fighting back against her claims he is a drug and alcohol abuser by claiming she’s obsessed with revenge and reality TV fame, RadarOnline.com can exclusively report.

In new Orange County, California court documents obtained by Radar, Matt says he no longer uses alcohol or marijuana, has never engaged in hard drug use, and is a “devoted father” to their three young children.

However, he claims his reality star ex, 35, is using his love for the kids as a way to be “extremely vindictive” in their divorce.

“Petitioner has historically been extremely vindictive and has used the children when she becomes angry or wants to control me,” he wrote in a July 30 declaration, adding that Gina has heightened the drama in a desperate grasp for fame.

“Petitioner has been acting erratically and in a way that I believe is unfortunately more based on a ‘storyline’ for her reality television show and not rooted in the best interest of our children.”

In his argument, Matt cited an exclusive Radar story claiming Gina was filming scenes about the arrest for the current season of RHOC.

He then said she was “irate,” and began “acting irrationally” and “completely erratic” when he stopped making payments for her car as decided in a December 2018 divorce settlement.

“She caused total chaos as we did not know if she was coming to pick up the children or not,” Matt wrote. “Petitioner texted my sister ‘Visitation will be revoked. He needs to get himself in order. He’s sick. Not broke.'”

“Petitioner demanding that my visitation with our children by ‘revoked’ simply because she was going to be required to pay her own car payment…is consistent with her historical vindictive mature and using the children as ‘leverage.'”

He then said Gina “threatened” his mother via text by claiming “You’ll see what happens next!” and sending a photo of fireworks going off.

“I am convinced that Petitioner is using any excuse she can to separate the children from me, as she knows that is my Achilles Heel,” Matt summed up.

Also in the filing, Matt confirmed Radar’s exclusive report that he was fired from his longtime job after the arrest, admitting he was “forced to resign” from his position.

As Radar extensively reported, Matt was arrested for domestic violence on June 22. Gina accused Matt of hitting, choking, dragging and even threatening to kill her in the terrifying fight. (He has not yet been charged with a crime.)

In the aftermath of the arrest, Matt was allowed supervised visits with the children.

However, after Gina claimed Matt failed to have a monitor during one such visit, she called for a judge to revoke visitation until the next hearing later this month.

A judge denied her request, and the couple will face off in court on August 14.
