It’s a tough day for the 90 Day Fiancé family.
The beloved father of cast member Elizabeth “Libby” Castravet — Chuck Potthast — has sadly passed away. Fans have followed Chuck for years, watching him show up again and again for his big, loud, and loving family. His loss has shaken viewers across the world.
On Sunday, November 23, Libby shared the heartbreaking news on Instagram. She revealed that her dad died on September 26, 2024, after a long and painful fight with glioblastoma, a severe and aggressive type of brain cancer. Chuck was surrounded by his family during his final moments. He was 64 years old.
“Two weeks ago, tragedy struck our family and it has left us completely shattered,” Libby wrote. “My sweet, loving, and caring dad went to heaven. We’re trying to figure out how to navigate our lives and move forward without him. Please respect our privacy during this extremely difficult time.”
Her comments were turned off, but that didn’t stop fans from sharing their love elsewhere on social media.
One viewer wrote, “Damn it 😭 I really liked Chuck. He was one of the good ones.”
Another added, “He was the best part of their story honestly. So sad.”
Someone else shared, “He was such a good father to her.”
And another wrote, “Uggghhh poor Chuck! I actually liked him on the show. This is sooo sad. May he RIP.”
Why Viewers Loved Chuck Potthast
Chuck became one of the most recognizable parents in the 90 Day Fiancé universe because of his daughter Libby’s storyline with her husband, Andrei Castravet. Fans got to know him as the emotional, hands-on dad who always tried to keep his large family together — even when drama pulled them in different directions.
He showed up in tough conversations. He tried to mediate family fights. And he always made it clear how deeply he loved his children.
Even off the show, Chuck touched the hearts of many viewers with his kindness, vulnerability, and openness.
His Quiet, Courageous Battle
Back in 2022, Chuck shared on 90 Day Diaries that he had been fighting cancer privately. Despite the difficult treatments, he still tried to stay positive. He continued sharing fun, lighthearted Instagram moments — including playful videos with his son-in-law Andrei.
Fans had no idea how serious things had become.
Just seven weeks before his passing, Chuck posted a cheerful update from a family boat day.
“Boating with the family !!” he captioned a smiling photo with Libby, Andrei, and their kids.
It’s clear that even in his hardest moments, Chuck held onto the joy of being with the people he loved most.
A Loss That Leaves a Big Empty Space
Chuck Potthast wasn’t just a reality TV dad — he was a warm, genuine person who many viewers felt connected to. He laughed, cried, loved big, and showed his heart openly. That’s rare on TV.
Now, his family — and the entire 90 Day Fiancé community — is grieving a man who made a real impact both on and off screen.
May he rest in peace.
