I think it's about finding that person who is the one, the love of their life, and if you have each others back and someone calling you on, you'll always be ok. I think Robbie wrote this about Nicole Appleton as he always referred to her as "The One" obviously that would be Ayda Field his wife now who is truly his "One". But anyone who has been in that situation of finding that person who completes everything can relate to the song and the lyrics.
