You can't give me what I want

You can't give me what I want
And I know that
I know that I can never be
Anything more to you
Than this
I am nothing more than this feeling
Of desperate lust
And tangled clothes
Submission
Satisfaction
Surrender
And yet
You reach for my hand
And squeeze it tightly
Look in my eyes
Hold the gaze
Start to say
Something
Then keep it back
And I know it can't be said
I know you can't tell me
Because no matter how much
I want to hear the words
It isn't true
And although you are
A lot of things
You are not a liar
You are my first choice
My angel
My last thought at night
And I am your fall back plan
Your booty call
Your last thought
As you kiss her on the dance floor
To just look at you
I would sell my heart
And you say
We don't have to do this
I don't want to hurt you
And the thought of not doing this
Not being close to you
Not feeling your heart beat against my chest
And your skin on mine
And your lips against my face
Would be much worse
You hold me as I cry
It's alright
No, it's not alright
How can it be alright?
I am in your arms
But I will never be
The voice in your head
I will never be the one
You call to say
I love you
Or I miss you
Or I want you
That won't be me
I will be gone
You will have moved on
With no backward thought
For me
As I let you practise love
And we have our fun
I am slowly dissolving
Eroding
Wearing away
Until one day soon
You will wake up
And wipe the dust from your body
And one day in years to come
You might remember there was this girl
Who was always there
When you needed her
And feel a brief pang of guilt
At not remembering her name.
