The former Saturdays singer has called time on her six-year marriage.
The pair were due to move to New York along with their two children, Aoife Belle and Tadhg before the decision was made.
A friend close to the couple told The Sun that Healy had her doubts about her spouse before they were to move to America: "Everyone was looking forward to the move but Una had become suspicious about Ben’s behaviour.
"She has now decided it’s over. She’s utterly heartbroken and devastated, but she’s very traditional in her outlook," they added.
The pair married in 2012.
Foden is said to move to New York without the family while Healy has returned to her family home in Thurles, County Tipperary.
