The singer, who joined Take That again in 2010 after 15 years of gap, might not be there for the band's seventh studio album, reports dailystar.co.uk.
"Robbie feels rejuvenated about his solo career. He feels on top of his game right now and wants to continue his solo success," a source said.
"Robbie's been back in the studio with Guy Chambers, who co-wrote most of his biggest hits - including 'Angels'," the source added.
However, if possible, the singer would love to juggle his time between his own career and that of the band.
"Ideally he'd love to do the Take That record and his swing album but that's just not possible - not when he's wanting to take time off to be a dad, too."
Williams has a 10-month-old daughter Theodra Teddy Rose with wife Ayda Field.
