In Season 4 of Welcome to Plathville, viewers watched Kim and Barry's marital struggles unfold. What it boiled down to was that Kim didn't feel valued or loved by Barry — to the point where she no longer felt an intimate connection with her husband of 24 years.

Although she repeatedly expressed her feelings to Barry through the years, there hadn't been a level of sustained, meaningful change in their relationship she was hoping for.

"As soon as he thought maybe it was working, he stopped trying," Kim explained on the show. "And once I realized that, I feel like emotionally I was just done. You know, I just feel like there's no way it's going to work."

Season 4 also saw Kim and Barry through various levels of separation — from sleeping in different bedrooms, to Kim staying at their various rental properties, to finally uttering the "D" word. On June 28, 2022, the Plaths issued a statement confirming their intent to divorce.

"After considerable thought and discussion, we have decided to end our marriage," they told People. "While this was not an easy decision, we know it's the best choice for both of us. We have been through many highs and lows in our 24 years of marriage and as we navigate this new chapter in our lives, we will co-parent our amazing children."
