Contextual Analysis of "do us part" in Lyrics

coming over to bend your ear -

are you hearing it loud and clear -

i'm sticking with you

'til death do us part

ah

ah

myself

yeah. till death

my love

i'll climb up that mountain

from now

and do you

sickness and health after all

till death do us part

Our teenage vow in a parking lot

I've seen the blues

until we're old and barely breathing

and the moment we locked eyes

nobody's ever gonna love you the way i do

and there you are

nobody's ever gonna love you the way i do

and there you are

for better or worse

i'll love you with every beat of my heart

and i swear like the shadow that's by your side i'll be there

i'll love you with every beat of my heart

for better or worse

i'll love you with every beat of my heart

and i will love you 'til forever

so take my hand and hold on tight
