The song could be about moving on after a break up.
"When can we get together again?
Nevermind, I've lost you"
She obviously left him, he still want's the girl, but it's too late. He fucked up and waited too long.
"I feel another
Time of..of my life
It's my body's plan"
He's proceeding to move on, as it is the only natural discourse. He's lost her indefinitely.
