What has come over you?

What has come over you
That you have done
This to me?
You were such a loving
Beautiful soul;
You are not anymore;
You loved me
And passionately too;
You no longer do;
I feel it in my bones;
Your heart is gone;
Flown out of the window
Of my life;
And I am left alone
Like a miserable soaked chicken;
Bathing in loneliness;
Feeling unloved
And abandoned for someone else;
My feelings are sad;
Why have you done this to me?
Love is a decision;
Why have you decided to love
Another after you promised
You would be faithful to me
And stay with me
Until death do us part?
How do you expect me to see you?
I am simply at a loss
What has come over you.
