Diamond was in a relationship with Australian Rae Farley that ended sometime before mid-2008. The two met in Brisbane, Australia, in 1996, and as of 2008 she ran his merchandising operation. The album Home Before Dark was written during Farley's struggles with severe chronic back pain, surgery and ongoing recovery. Diamond said, "She had back surgery and it wasn't going well. She was in extreme pain for a year and the surgery did not really work. If anything, it made it worse. And I never left her side. I was within twenty feet of her for the entire year that I took writing this album."
