Map to my heart

He took it,

That map to my heart,

And cupid,

Shot me with that dart.

Now I'm under his spell,

Falling so deep,

Until he lets me go,

And I am left to weep.

I dont think he'll find it,

Or even try,

I just wish he had the decency

To tell me goodbye.

I've lost it,

That map to my heart,

This boy has it,

I think he ripped it apart.

And cupids arrow,

Is still stabbed in my back,

Now my heart is breaking,

WIth every little crack
