He said both boys had been so excited and had been snorkelling in shallow water as they sorted out their towels and bags on the beach when the boys got into difficulties.
Both parents went into the sea and tried to save them as they were swept out by the current, he added, and the whole ordeal happened in less than 10 minutes.
Nathan said the loss of his 36-year-old “childhood sweetheart” was “unimaginable”, but she was a “hero… in life and in death” as she helped to rescue the two boys.
“I’ve known her since infant school,” he told the BBC. ” We first got together when we were 14… so 22 years.”
“There are no words I can use to describe Leanne, same as anyone she has ever known.
“She was the purest of people, the most generous kind and beautiful person who ever walked the earth.
“Our relationship was perfect. She was the perfect mother, the perfect wife the foundation of our entire family.”
Nathan said: “Royal Caribbean and Virgin Airlines were absolutely incredible to us and made an impossible journey home so much easier.
Now, as he “keeps strong for his boys”, a gofundme has generated nearly £9,000 in donations to support them.
