My heart is torn in 2

I've got a girlfriend
She's got an adorable smile
the cutest laugh i've ever heard
for me she'd run a mile

She's got stunning eyes
and a nice warm hold
i know she'll be there
to protect me from the cold

But there is this other girl
thats always in my head
she's the one thats on my mind
before i go to bed.

Me and her have a past
it was my fault we lost it all
i was so Young and naive
and i let our feelings fall

i didn't think me an her would work
i didn't think we'd last
i wish i hadn't told her
we need to keep us in the past

She retaliated with harsh words
words that made me cry
we were both so angry
that we didn't even try

but then one day she called me
regrets letting me go
my heart starts to race heavy
my stomach's sinking low

My girlfriend will look out for me
she says everything she should
she tells me that she loves me
and i know she'll treat me good

But no matter how perfect
my girlfriend seems to be
she'll never be Renee
and that i can guarantee
