They are said to have called off their 18-month romance due to the pressures of his time on X Factor.
And following his win with boyband Rak-Su this weekend, Myles Stephenson has reportedly dismissed hope of a reunion with girlfriend Rebecca Bignell, because it would be ‘selfish’.
Insiders claim that Myles is conscious of hurting his ex-partner because he cannot commit to a relationship at this time.

A source told The Sun on Wednesday: ‘Myles wants to protect Rebecca as much as possible. He cannot commit to a relationship. He needs to be single right now.
‘Rebecca is a very important person in his life. He is conscious that he doesn’t want to hurt her by giving her false hope.
‘It would be selfish for Myles to lead Rebecca on. The time is not right. But who knows what will happen in the future. Never say never.’
MailOnline has reached out to a representative for the band for further comment.

It follows claims that the duo were headed for ‘crunch talks’ in the coming weeks with a view to reconciling.
Myles and Rebecca’s relationship fell apart in September when he stepped back from the relationship to focus on his music but they officially split in November.
They had been together for a year and a half and known each other for nine years before.
The duo stayed on good terms, and she has continued to promote the band’s music as well as visit him at the studio during the live shows.

Sources close to Sony music boss Simon Cowell – the Rak-Su mentor – have also reiterated that the boys’ focus should be music.
During the competition, it was claimed that Myles had grown closer to a female production staff member but that was later denied, with reports that he was ‘completely single’.
A source said at the time: ‘Rak-Su are the favourites [to win] and Simon’s priority – he doesn’t want anything getting in the way of their focus.’
