The 37-year-old singer reunited with the man-band for the album Progress, and a subsequent tour that ended last week.
And now that he's a free agent, Robbie said that the time has come for it to be all about him again.
'The gigs have been absolutely amazing - the best period of my career so far with those boys,' he told The Sun.
'Sharing it with somebody is much better than doing it by yourself, but then ego, want, need and a whole heap of other things kick in.
'And you start preparing for your own tour... and the other boys are going away for a bit and I don't really know what's on the cards with them.
'But we have to ride again, we have to - it's too much fun.'
