Your promises were just a smoke screen

I was a clear sky
My expectations on you were too high
I considered you to be my bright Sun
But you just came to have some fun
Your sugar coated words
Flew far away like birds
You pretended to be my light
And turned my life into a dark night
Now, crowded with black browed cloud
I still say that'I love you' crying out aloud
Your presence was treasured in my life
But all you did was stabbed me like a knife
You showered me with all your love
What made you betray me now ?
