When you follow a reality show for years, some cast members start to feel like family. And for many chuck 90 day fiance fans, Chuck Potthast was one of those people — warm, emotional, and always trying to keep his big family together.

Sadly, the chuck 90 day fiance community is now mourning his loss.

Libby Potthast Castravet, Chuck’s daughter and longtime cast member, shared the heartbreaking news that her father passed away on September 26, 2024 after battling glioblastoma, a fast-growing and aggressive form of brain cancer. He was 64 years old and surrounded by loved ones during his final moments.

As someone who’s written about reality TV families for years, I (Ammar) can honestly say Chuck was one of those rare people who felt genuine, even through the screen. His loss hits hard.

Libby Shares the Heartbreaking Announcement

On November 23, Libby posted a quiet, emotional update on Instagram. She poured her heart out as she explained just how much their family is hurting.

“Two weeks ago, tragedy struck our family and it has left us completely shattered,” she 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.”

She asked for privacy as they grieve — and turned off comments to keep things peaceful.

And honestly, you can feel the heaviness in her words. Losing a parent is never easy, and losing one who was the emotional center of a big family is even harder.

Fans Share Their Love After the News Breaks

Although Libby disabled comments on her post, fans found other spaces online to express their love for Chuck.

A few comments shared by fans included:

  • “Damn it 😭 I really liked Chuck. He was one of the good ones.”
  • “He was the best part of their story honestly. So sad.”
  • “He was such a good father to her.”
  • “Uggghhh poor Chuck… I actually liked him on the show. This is so sad. RIP.”

As someone who follows these communities daily, I’ve seen very few side characters loved as much as Chuck. He had this gentle, emotional way of talking that made viewers root for him.

Why Fans Loved Chuck Potthast So Much

If you watched Libby and Andrei’s storyline, you probably remember Chuck popping up in some of the most dramatic moments. But what made him memorable wasn’t the drama — it was his kindness.

A Familiar Face in the Potthast Family Storyline

Chuck appeared in many episodes of chuck 90 day fiance as Libby navigated her relationship and eventual marriage to Andrei Castravet.

Over time, fans came to know him as:

  • The emotional dad who cried openly
  • The peacemaker in a loud, opinionated family
  • The supportive father who tried to help everyone
  • The person holding the family together during conflict

He wasn’t perfect — none of us are — but he always tried to show up with love.

As a blogger who covers TLC shows, I can tell you: not many cast parents become fan favorites. Chuck truly did.

His Private Battle With Cancer

Back in 2022, Chuck revealed on 90 Day Diaries that he had been quietly fighting cancer. He didn’t talk about it much because he didn’t want the world to see him in pain.

And yet, even while going through treatment, he continued posting lighthearted videos — often joking around with Andrei or documenting family moments.

That alone tells you the kind of person he was: someone who stayed positive, even when life got heavy.

His Last Public Update

Just about seven weeks before he passed away, Chuck posted a cheerful family photo from a boat day.

Boating with the family!!” he wrote, smiling alongside Libby, Andrei, and his grandchildren.

Even while battling one of the hardest illnesses anyone can face, he tried to enjoy life. He tried to enjoy the people he loved.

And that’s something all of us can learn from.

Chuck’s Legacy: More Than a Reality TV Dad

When someone passes away, what stays behind isn’t their fame — it’s how they made people feel.

Chuck’s legacy includes:

  • His kindness

  • His love for his children
  • His willingness to mend relationships
  • His efforts to keep family at the center of everything

Whether you’re a chuck 90 day fiance fan or not, Chuck’s life reminds you to cherish moments with the people you love. And as I’ve learned as both a blogger and a human being, those moments matter more than anything.

Chuck Potthast wasn’t just a reality TV figure — he was a father, a grandfather, a friend, and a fighter. He faced cancer with courage. He loved his family fiercely. And he touched the hearts of viewers around the world.
