I agree that there are a number of meanings to the song and I agree that the song's meaning is individual to the person.
Regardless of what inspired it, this song was our first dance at our wedding. My wife transferred colleges across the country so we could be together; despite a lack of support from most of our family members.
We translated this song as a plunge into uncertainty with almost unrealistic optimism that requires both of us to completely commit to each other (if you're going to fall I will let you know that I will pick you up, like you for I), we loved each other and it killed us being apart (we're all working toward this goal), we were starting our lives together, bound in marriage (here we go, life is waiting to begin), and that we both need to be equally committed (I cannot live, I can't breathe unless you do this with me).
We're both in the military, we've been together for 5 years, we've spent almost 3 of those years apart, and I'm getting stationed with her in two months. I'm sure it was inadvertent, but no other song so eloquently described the love my wife and I have for each other.
