Who's that girl?

What i really feel about his girlfriend and his "feelings".

Who's that girl?
And why is she standing right next to you?
Tell me how you feel
It’s your heart that she wants to steal

Why am I living a lie?
The truth in my eyes are hiding from you
Why must I
Contain these buried cries?

Chorus:
No she can’t be the one that you want
Now all I hear from myself are taunts
I've fallen between all that’s misled
But it’s still the image of you that’s trapped in my head

It's hard for me
To write this song about you just to mend
I remember
What you said

You told me
That you would always be there
But where are you now?
Are you with her or lost inside yourself?

Bridge:
Open your eyes
Open your eyes
Smother your tears in your own devotion
Shut the door
Shut the door
You don’t need the tides in the ocean

Chorus II:
You’re all that she wants; you’re all that she’ll need
Though there’s someone else you want heed
Is it her? Or is it really me?
I don’t want her shadow to fill, I want to be free
