Unexplainably Explained

We had lot of good times,
We had lot of fun.
We were together
When we were all alone.
But now I'm confused
But now I'm scared
Is this the time to again say a goodbye
Is this the time to again cry
I cant stand away from you
After holding your hand in shade and sun lights.
But i cant stand see you with the guy
Who brought rain into my nights
I wanted to move on
I wanted to start again,
I wanted to be your loving friend
I wanted to be precious again
But I'm a diamond which has turned into a stone.
But never realize i can be replaced so soon.
So here i say goodbye
So here i see you for last time
Maybe this poem doesn't rhyme
But may be it says all my heart wanna sign.
