Understand - Ice Station Zero

We don't see eye to eye anymore
And often I'm wondering what we're fighting for
Though I haven't changed, I'm not the same
I still look to you, to guide me through
Through thick and thin, I'll rebegin
It's nothing I haven't felt before

Could you understand
Life on this screen, it's not as it seems

We're on two such different plains
And every conversation always ends the same
I may not be what you want me to be
The future will always be a mystery 
Just let it go, be on your way
I'll fill the shoes you're wearing today
You can't say what you want to
‘Cause it will come back to haunt you
You've come so close to me
But now you're not the same to me

How could this be?
