The family of tragic financier Brandon Miller is heartbroken after his widow, Candice Miller, skipped his tombstone unveiling ceremony over the weekend — because, insiders say, she’s angry about their stunning financial collapse.

The real estate broker killed himself last July at their Southampton home as the house of cards that supported their expensive lifestyle began to collapse under the weight of multimillion-dollar debts and various lawsuits.

At the time, a representative for luxury influencer Candice said in a statement: “Candice is devastated by the loss of her soul mate, and her two young daughters’ lives are forever impacted by the loss of their beloved daddy.”

It was reported at the time that Candice was unaware of their dire financial straights.

On Sunday, Brandon’s family gathered on Long Island for his headstone unveiling, a Jewish rite that’s usually held within a year of a death. It doubled as an unveiling for his mother’s headstone, since she died just six months after Brandon.

We’re told Candice was in the New York area over the weekend.

“It was an incredibly emotional and moving gathering, with family and close friends coming together to honor their memory,” a family insider told us. “There wasn’t a dry eye as Brandon’s closest friends stood by the family to pay tribute. His sister, Maurley, spoke with heartbreak and grace, honoring the two people she’s lost in just six months.”

They added, “While Brandon’s wife, Candice, and no one from her side of the family attended, the presence and loyalty of those who did was a powerful reminder of the kind of man Brandon truly was — and the love he left behind.”

She sold the house where they had lived for $15 million and moved to Miami.

They were married in 2009. They have two preteen daughters.

A rep for Candice, who ran the popular luxury lifestyle account Mama and Tata before the tragedy, didn’t comment.
