Kim says that after raising a gaggle of kids, she’s ready to live her best life. This is exactly why she opened the Grady Central Dance Studio in Cairo, Ga.

"I've always wanted a space like this. One, because I want adult ballet classes, and I can't take them anywhere in South Georgia," she explains. "I just want a place where the community can come and move and interact and have a great time."

But as her career is on the rise, her marriage seems to be crumbling. Barry says in the episode, “Sometimes I feel like I'm in a marriage Twilight Zone.”

"In some respects, I'm feeling left behind," he adds. "I've always thought marriage would be 'til I die, but in reality, it looks like it could end. Soon.”

New episodes of Welcome to Plathville air on Tuesdays at 10 p.m. ET on TLC.
