What happened?

It all happened so fast that night
yet every detail I still see
One minute we're best friends talking
the next you're inside of me
You lured me in with your touch
and such a hungry kiss
but the gentle look in your eyes
is what I will mostly miss
you smiled and leaned over to me
and whispered in my ear
you sent chills down my spine
and told me what I wanted to hear
"You're so beautiful and firey
I can see flames burning in your eyes
let me tame that red hot flame
I'm not like the other guys."
WRONG! you were even worse
I can't believe I let you in
and worse you lie to deny it all
now all I feel is sin
It started as a friendly night
We got together just to talk
We opened up to each other
and connected as we walked
You told me how you missed me
And the way our friendship used to be
And though you had a girlfriend
You wanted my serenity
You took advantage of the love
That I was willing to give
Now youre trying to convince me
To move on, live and let live
I let you in and you tore me down
What a big mistake
Now I will forever regret
The innocence I let you take
