A heart burned to ashes

I've felt the cold
for a bit too long
as the warmth rolls over,
am i on fire or is it just too cold?
please someone thaw out my frozen heart

Don't say you promise
those don't mean a thing
trust belongs to the following words
"cross my heart,
I'm going to die,
and for once,
I really don't care."

Now i'll forgive you
my hearts getting warm
just then i realize
the sensation is fire
and my heart is burned to ashes
