Ronan - who has kids Jack, 13, Marie, 11, and six-year-old Ali with Yvonne - said: “I haven’t written songs about anyone.
“I’ve hurt enough people. I’ve caused enough trouble and heartache.
“I don’t want to do that on this record. I want calm. That’s where I am."
In 2009, Ronan's Boyzone bandmate Stephen Gately died suddenly from a pulmonary oedema and the singer admits his pal's passing made him more determined to live life to the full.
He said: "When Stephen died, everything changed.
"I had never lost anybody that young. It brought the rest of the band together, like brothers, and taught us all that life is so fragile. Perhaps it's a cliche, but it became important to live every day to its best."
