Do I mean anything to you?

So I am your girl
But you ain't my man
You belong to her
And I get what I can

I know my place
I know where I belong
I know that what we have
Wont last for long

But how I wish I knew
If you loved me too
I know you care
But is that all you do?

You act like I am yours
Even though I am free
Because if I am nothing
Than what else can I be?

I am free to chose
The man of my dreams
But the guy I am looking at
Is not who he seems

He doesn't treat me
The way you treat me
He doesn't care
About what we can be

He doesn't touch me
The way you do
His caresses are rough
Compared to you

He doesn't listen
To what I have to say
But somehow I am stuck
On loving him that way

But you have changed
My perspective in life
I no longer crave
To be his wife

Because now I look at him
And he has nothing on you
He could never give me
All the things that you do

So I am satisfied
With getting it on the side
I'll show my love for him
And my love for you I'll hide

Because thats all I am to you
A friend that you can have
In bed or on the job
Breaking my heart in half

So for every kiss you give me
I feel like I could fly
But with every goodbye you tell me
I feel the need to cry

I don't know if you understand
I myself am so confused
Because one minute I feel loved
The next I feel used

I know you give me all you can
Without breaking her heart
But instead you hurt mines
And tear it all apart

I know that its her
Who hold s the key to your heart
I know that I am just a temporary thing
And that soon we will part

It just hurts not knowing
If you care about me the same
If this means something to you
Or is it just a game
