Why is it that you won't love me?

Oh sure you love me when we are alone 
Out in the world we are off limits
I want so much to tell the world that we belong together
I want so much for you to see what I see
It's been almost two years that we have begun
and who knows when or if we will end
For now I hold on to the time we share
in hopes that one day the world will see us together
the way it is meant to be
You loving me like I love you
