Understanding lyrics

You're here, but what if you weren't
What would have happened to me
That candle, unburnt, is history
One thing I guess this place would be a mess
For my standards at best are undemanding
And that takes some understanding
[ Lyrics from: http://www.lyricsmode.com/lyrics/e/everything_but_the_girl/understanding.html ]
Still here, but what if we weren't
Where'd you think I would be (where would I be)
For love I have learned depends on geography
Fortune found us when all around us
Half the couples we knew were disbanding
And that needs your understanding

And do you know even when we disagree
And freedom holds out a hand to me
You know I would nver want to be without your company
And I mean that totally

We have reached an understanding...
Understanding, understanding...
