Undefined lines.

Im waiting for you
on the steps again
Hoping you'll look through
You window and see me here

Cause I've got somethings to say
To you, so listen up
I realized today what this feeling is
I noticed again Im feeling it all the time
& I decided its time to tell you
Cause you need to know...

Im falling with you so fast so hard
Cant change my mind about this
Dont waste your time
Trying to ask
If Im sure
Cause I am
Oh yes I am, so sure about you

Im fallling inlove so hard
Can't break the rhythm
of my pounding heart
Just think about
All the times we've been together
Can you think of a different explanaton'
If so Id love to hear it....
Cause I am fallling so inlove so inlove with you
& I cant stop it, not matttewhat I do
& Ive tried everything
So please tell me that you feel the same
but even if you didn't, my heart wouldnt change.

Undefined lines, of where it goes
from liking to loving
& confused to knowing
I love it, when you say it
straight up, no going back
I love you.
