Despite her husband's absence, the family has continued their holiday routines, the Orlando Sentinel reports.
‘We do both Christmas and Hanukkah, just as I always have,’ she told the local newspaper.
‘We have a Christmas tree and I celebrate with the children and light the menorah, too. It's a really special tradition this time of year.’
Her 35-year-old Brazilian-born husband disappeared on June 19.
The couple's $5 million dollar mansion, Lazzara yacht and the motorboat that washed ashore without Mr Aguiar have been put on the market and all remain unsold.
During the couple’s often tumultuous marriage, Mr Aguiar was committed to a hospital for mental health-related reasons, sued his wife for divorce and later withdrew that petition.
He was on probation for domestic violence when he disappeared.
Mrs Aguiar last April sought a judge's opinion on whether their prenuptial agreement was fraudulent.
For now she is focusing on giving her kids a good holiday season, and keeping those blessings in mind, according to the Sentinel.
‘I have to do that multiple times each day, when things aren't looking so good. That's how I get through the day,’ she said.
Last month, lawyers for Jamie Aguiar implied that they believe her husband may still be alive and well - and hiding out in the Netherlands.
They are speculating that Mr Aguiar could have faked his own death to avoid losing his $100 million fortune.
An attorney for the man's wife has told reporters that the missing man's sister intends to move to the Netherlands, raising suspicion that she could be planning to rejoin her brother, who could have relocated to Europe.
A close business associate of Aguiar also resides in the Netherlands, the lawyer added.
The multi-millionaire had reportedly argued with his wife, when she is said to have threatened him with a divorce, hours before he disappeared.
Mr Aguiar, a father of four, had filed for divorce last July but did not go through with it.
