Not 'Cause I Wanted To Lyrics

Well I'm calling you
cause you deserve to know
you are not the reason I had to go,
late at night in the hotel room
I think of all I've lost,
what I've put you through
and if I knew the reason
I would tell you why somehow
the feeling slipped away
I only did what I had to do
not cause I wanted to.

I've got a guilty heart
and a troubled mind
no matter where I go
you're never far behind
I'd like to think that you'd forgiven me
but forgiveness ain't enough
to wash my conscious free
Oh if I knew the reason I would tell you
why somehow the feeling slipped away
I only did what I had to do
not cause I wanted to.
