The Dubliners, who was previously member of Boyzone, joined forces with former Westlife singer Brian McFadden in 2016, and the pair have been performing as super-group Boyzlife ever since.
But Duffy said that the duo prefer not to speak to the press or do concerts in Ireland anymore because “people don’t listen and they insult” them.
“We don’t do anything here. That’s our choice,” the singer told the Irish Mirror.
“We just wanted a peaceful life, we love what we do. We’re very successful in the UK. They champion us over there and they bring out the best of us.
“You come over here and whether it be radio DJ’s or certain journalists, they write derogatory terms. They’re just negative.
“Boyzone was the same and when we came back together in 2008, I never worked here again. It was always the UK, Australia, Middle East, Europe.
“Brian and I are just back from Cape Town, we’re on our way to Indonesia now to Bali and then we’re off to Vietnam and Cambodia. Then we’re off to Bahrain, Dubai and Abu Dhabi but we do nothing in Dublin.”
“It really is just begrudging. People don’t listen and they insult… People assume it is going to be s***e because they don’t like us from the days of the 90s.”
The 47-year-old said that he doesn’t go out in Dublin much for the same reason, adding that he’s sick of people “slagging me off.”
“I rarely socialise in Dublin because when I go out, you don’t know if someone is going to buy you a pint or give you a dig,” he explained.
“My kids are all grown up now, my daughter is 22, Jay is 26 – they don’t want to be reading s**t about their old man in the paper. They don’t want to hear DJs slagging me off so it’s just easier for us.”
However, he insisted that he still loves his hometown, but said that he wishes people would be kinder to one another.
“My home will always be Ireland. Dublin - I love it. I’m very passionate about Irish people and Ireland and I think we have a fantastic hospitality about us but we’re horrible to our own, we’re horrible to ourselves.”
