Contextual Analysis of "i didn't know" in Lyrics

am i doing something wrong?

i'd be alone

start

you thought i didn't know you

the things i do for a kiss

i didn't know when to give it up

now this is a song with a message

i didn't know

oh

don't need no butterflies when you give me the whole damn zoo

filled my glass up past the rim

i didn't know you then

i never thought he'd be.an old man

all those years ago

start

what love meant before

or picture of the past

know

didn't realize i was lost till i started lookin'

i didn't know i was a cheat till i fixed the deck
