Kathryn Dennis and Thomas Ravenel are over -- and this time it is for good.

During a new interview, the Southern Charm star explained that despite her and Ravenel's habit of breaking up and making up, their relationship has come to a sure end.

"I know I've said that a lot, but we are definitely, officially, over," Dennis told Bravo TV's The Daily Dish on Monday. "Taylor Swift said it: 'We're never, ever, ever getting back together.'"

"It was a long time coming. I think what really motivated it was that I had Julien in November, and I had hoped that having two children, something would fall into place somehow, magically," Dennis said. "[Thomas] was talking about marriage in the hospital. He really wanted to make it work. And then he just flipped a switch, changed, and I don't know. I kind of was just realizing my kids were more important than the way I feel about him romantically."

In addition to son Julien, Dennis and Ravenel are also the parents of 2-year-old Kensington. However, when it comes to co-parenting, things between the two haven't been great.

"I will be honest. There's been questionable behavior. I'm sure people see it on social media, every platform he blasts me on," Dennis said. "So that's not been fun, but you know, hopefully he'll get over that."

Dennis went on to reveal that despite facing hard times, her former partner and the father of her two children has not been too helpful. In fact, she claims he doesn't check out her at all.

"I've gone without electricity. I've gone without heating and air," Dennis stated. "He doesn't even ask me if I'm OK. He doesn't care at all, but that's fine. I'm gonna make it work on my own. I always have, and I'll figure it out."
