Contextual Analysis of "i couldn't help" in Lyrics

she had the kind of smile to where you couldn't tell

i couldn't help myself. she had the reddest lips

as they come

no

i saw you from across the room

you got me staring

well i'll just tell you now

i just fell in love and i couldn't help myself

how could i not want you here and be that selfish

naw mean i couldn't help it

i helped myself

i tell myself

what a way to say

for my foolish ways

you throw up with your face down

i couldn't help but think of how you kiss

but she can't find the words

how can i when i feel this way?
