The Irish singer, who split with the PRIDE AND PREJUDICE star three months ago, believes their relationship suffered because neither would admit they were falling in love.
And now he wants to start afresh.
He says, "Things are never as straight forward as they seem.
"No matter how long you've been with someone, you're wary of letting your guard down. You don't want to say you love them or admit you're wrong.
"Let's just say that I hope things work out."
