The popstar has never given any explicit reason for his decision to dump Price last May.
However, speaking about the break-up in a new interview with the Daily Star, Andre remarked: "When you see the whole story you'll realise why I lost all [my] confidence. And I do think it will come out eventually, just not from me."
Discussing the success he has enjoyed since the split, he commented: "My fans have been out of this world. I just don't see the hype. I wouldn't even notice it unless someone physically came up and said it to me.
"I think I have always been self-doubting. I guess it can be a sign of weakness but you don't get cocky in this business being like that.
"I'm not arrogant and the nicest feeling in the world for me is someone saying, 'He's a nice bloke'. That and someone saying you're a good dad."
Andre has previously promised not to reveal "incredible stuff" about his marriage to Price and recently said that his new book will not focus on their break-up.
