Southern Charm‘sKathryn Dennisis remaining focused on her children’s wellbeing in the wake of their fatherThomas Ravenel’s arrest.

Hours after Ravenel, 56, wasarrested and charged with assault and batteryin the second degree on Tuesday, his ex Dennis shared a photo of the former couple’s two kids — reminding her followers thatKensie, 4, andSaint, 2½, are her main priority.

“Everything in life to me,” Dennis captioned a sweet, smiling photo of Kensie wearing a Miami Dolphins cheerleader outfit and Saint sporting a blue polo shirt and khaki pants.

Dennis also tweeted about people protesting Brett Kavanaugh’s Supreme Court nomination: “People are on the side of the road with signs saying “#believesurvivorsin mount pleasant.”

Two months ago, during the season finale ofSouthern Charm,viewers learned that Dennis hasreceived 50/50 custodyof her two children with Ravenel.

The change was a big victory for Dennis, who lost custody andentered rehabin 2016 after she tested positive for a drug.

Dennis previously opened up to PEOPLE aboutthe painshe felt when shelost custodyof her children.

“It’s absolutely not something I thought I’d ever face. It all happened so fast. Losing my kids, I just remember falling on my knees and breaking down like every single day,” she said.

She added: “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.”

ButRavenel’s arrestposes a serious question: Could Dennis be awarded full custody moving forward?

On Tuesday, Bravo exclusively confirmed to PEOPLE that Ravenel will not be returning to the reality series as a cast member.

The network’s decision comes after Ravenelsuggested he was quittingin August, tweeting “I’m not doing the show anymore. In the contract they have the right to fictionalize your story. They took advantage of me. I decided I’ve got too much to lose and informed them I’m not coming back.”
