Contextual Analysis of "i'm pretty sure" in Lyrics

if you're looking for something beautiful

walking away from you like i should

and i don't see things the same as i did from down there on your floor

take back that photograph with your pretty little red dress on

for not feeling like i do

even though down deep in my soul it feels like it might

i'm so sick of you just playin' games

i'm pretty sure i love you

i know you're not mine

all that did was left me feeling crazy

i've never looked to this deep into myself before

then again i could be. wrong

i'm crazy about ya

tomorrow morning is our wedding day
