Ronan Keating's wife can't forgive his "emotional" infidelity.

Yvonne Keating was left devastated last month when it was revealed the Boyzone singer - with who she has three children, Jack, 11, Marie, eight, and four-year-old Ali - had cheated on her with 26-year-old dancer Francine Cornell, and is reportedly finding it harder to deal with as there was more to his affair than just sex.

According to the Mail Online website, she told a friend: "It'd be one thing if it was just sex, but this was emotional."

The former model - who made her first public appearance since splitting from Ronan at Westlife's show in Croke Park, Dublin, Ireland, on Saturday (05.06.10) - is said to be particularly upset that the 'So Good' hitmaker's several-month affair was an open secret between his bandmates and tour crew.

A source said: "Yvonne is heartbroken because she thinks all of Boyzone knew and no one told her.

"That's really hurting her now, because they were all so close. She said people can get over a one-night thing, but is wondering how she can ever get by this."

It was recently claimed that Ronan regrets his affair, but still hopes to save his 12-year marriage.

He was quoted as saying: "She meant nothing - it was just a fling and a mistake.

"It's cost me the thing most dear to me in the world. I've wrecked everything. I just hope it's not too late."
