I always figured this was about a relationship in which the "she" was much more sure about the long term than the "you" the song is addressing. "You" just keep following her lead, drifting into the life she's planned for the pair of you. "She's" in charge, and she's fast-forwarding the relationship...pushing to move in together, or get married, or have kids. It's bizarre to you how much she's mapped out ahead.
Then the surprise, at the end -- none of this was "your" idea, but you're content to be a passenger in the relationship...at least for now.
