I promise I will die!

If there come a time
When you say she is yours
I promise I will die
Unknown to many cures

I can't have you with her
Not after all we've been through
Me and her have history
That's the same for me and you

I know hanging onto you is wrong
But I can't stand to think
Of you and her holding hands
It is death that I am on the brink

I'd cry a thousand tears
I'd write a thousand rhymes
If I knew it would change anything
If it could turn back the times

I'm not trying to change your mind
All I'm doing is letting you know
I promise I will die
If you and her do!
