Dying inside

I see you with her
I die inside
You turn around
But dont see me cry
There's nothing in this world
That I can do
To take away this love for you
I want you you to look at me
But you turn the other way
There's so much out there
Left for me to say
But either way
You won't care
You'll turn around
And won't see me crying
But next time you see me
I will be dying
