sposa son disprezzata

I saw my friend perform in a ballet this week.  One of my favorite parts was danced to a piece by Vivaldi.  I really resonated with the story depicted by the couple dancing.  Later, I looked up it's meaning and understood why.  Here is the translation from Italian to English:

I am a scorned wife,
faithful, yet insulted.
Heavens, what did I do?
And yet he is my heart,
my husband, my love,
my hope.

I love him, but he is unfaithful,
I hope, but he is cruel,
will he let me die?
O God, valor is missing -
valor and constancy.
