I agree with everyone, that it's about how he misses his girl at home...but by the end,
"All my time spent wondering
Why I stay true to you
'Cause you're not here, and now it's clear
I'm never going back to you."
It sounds like he's saying 'I try so extremely hard for you even when I'm out touring, but you don't have the patience to wait for me' ...it implies she has cheated on him and he kinda knows, hence he's never going back to her
