The pop star tied the knot with actress Ayda Field at their Beverly Hills home on August 7 and thinks the greatest benefit of having a wife is knowing you have someone to constantly support.
He said: "Married life is a bit wonderful to be honest, yeah, it really is. Stability and happiness, I-m getting used to it but, you know, it was bound to happen at some point.
"Life feels different, there`s like 15 per cent of rubbish that you`re carrying round with you, well me anyway, that`s just disappeared. It`s great being part of a team."
Just as Robbie is enjoying the support he gets from Ayda, he admits it is great being back with his Take That bandmates - Gary Barlow, Mark Owen, Jason Orange and Howard Donald.
The reunited members have recorded a new album, `Progress` - their first as a five-piece since 1995`s `Nobody Else` - and the 36-year-old singer has had such a great time he is keen to stay in the band.
Speaking on British station BBC Radio 1, Robbie - who walked out on the band shortly after `Nobody Else` was released to pursue a solo career - said: "I`m not really sure how long it`s going to last to be honest. We had a lovely band meeting the other day - which lasted a couple of hours and you scratch your beard and talk through how you`re feeling with things. And I was thinking, `I want to do this again,- but we-ll see. Who knows? We-re free to do whatever we want, only time will tell."
