how can I?

tears stream, down your face,when you lost something you cannot replace-Coldplay 'Fix You'-

Cannot touch, cannot hold, cannot be together
Cannot love, cannot kiss, cannot have each other
Must be strong and must let go
Cannot say what our hearts must know

Cannot dream, cannot share, sweet and tender moments
Cannot feel, how we feel, must pretend it's over
Must be brave and must go on
Must not say what we've known all alone

How can I not love you
What do I tell my heart
When do I not want you
Here in my arms

How does one walks away
From all of the memories
How do I not miss you
When you are gone
