disappointment in love prayer

Lord, I am in my room alone;
It's dark, and just You and I are here.
I keep thinking about this past day,
and how hurt I was when I saw (his name)
talking with that other girl.
I thought (his name) was the greatest.
He was always so nice to me.
Now nobody else exists for him, except that other girl.
Lord, It is so hard when you love someoneand they don't return the love.
Is this the way You feel, Lord,
when You love us so, and we don't return the love?
