To love what is not mine to love

Why do i think of you
when I know you're hers?
I see her in your arms
and i see your lips touch
yet despite all of this
I can't keep you out of my mind

the world seems to spin
When you talk as sweetly as you do
But then she approaches
and takes you for her own
And inside I am dying

Is it obsessive?
to love what is not mine to love?
Is it possibly true
that it's an unrealistic fantasy?
Do you not feel the same?
These emotions so intense
must be two-sided right?
If not I'll surely die
Thinking of love not being neutral

somehow i know she knows
that secretly i want you so
and i know you know too
But yet you don't respond to my feelings

so for now I'll just watch
Crying as you hold her gently
As I wish you'd hold me
thinking of us together
Knowing you're relationship was just a charade
and you're really mine forever
