"happy accident" lyrics

What's the point of this if I know how it ends?
You said I got the spark, well baby, are you the flint?
And don't you dare me to 'cause you know that I will
And don't you say those words, that ain't part of our deal

Walk five miles from my door just to give you some more
Do you just talk to me when you're lonely and bored?
And don't you act like that when you know what I feel
And don't you tell me to stay 'cause you know that I will

But you get so close
I almost don't bite my lip
Happy accident
And I wanna die when you say don't cry
I won't quit
Happy accident

Always measure my time by the way you spend mine
I wanna burn it all down, could I borrow a light?
And don't you dare me to, I could leave in the night
And don't you dare me to 'cause you know I could fly

But you get so close
I almost don't bite your lip
Happy accident
And I wanna die when you say don't cry
I won't quit
I'm no accident

What's the point of this?
I don't know how it ends
