Invisible?

I'm quiet,
not blind.
I can see the wonder in your eyes
and the curiosity in your tone.
She flaunts her beauty
and desire fills your soul.
But I stand silent.
Although you're clearly missing view of me,
I see it all,
I hear it all,
Worst of all,
I feel it all.
I feel it because that's what you once had for me.
Now it's hers.
You are hers.
She got your laughs,
your tears,
you love.
It was mine.
Snatched up from right under me.
Must be like taking candy from a baby.
