Where's your love? Is this it?

As I walked at this dark valley,
I wonder why I am with you,
im so sick of you,
as I say these words you might feel happy or sad..
Now as we walk at this dark valley,
I noticed as we go further your moving away from me...
This makes me think that as time pass by your love for me is fading away,
But you still keeping say that you love me.
who should I believe you or my heart..
Maybe your just lying..
or Maybe pretending..
