She said she loves him, but she is gone! What the hell does that mean?

The NA NA NA Song
Na Na Na Na Na Na, she gone, she gone, she gone away
Na Na Na Na Na Na, doot do do doo
Na Na Na Na Na Na, she gone, she gone, she gone away
Na Na Na Na Na Na , doot do do doo
I met a girl so long ago, why she had to leave well I don’t know
She said she loved me, but what does that mean, if she’s not here to tell me so, oh no
Na Na Na Na Na Na , She gone, she gone, she gone away
Na Na Na Na Na Na , Doot do do doo
Na Na Na Na Na Na. She gone, she gone, she gone away
Na Na Na Na Na Na. Doot do do doo
I have one unanswered prayer, for just one more day with her, hell yeah,
Would mean the world to me, but what does that mean, if she’s not here to tell her so,
I’ve got to tell her so
Well she was mine, lord it only seemed like a minute, then she was gone, gone in one seconds time
Well I fell down, I fell down and I cursed the heavens
What’s the ultimate price you’ll pay for a sinners life
