Lyric discussion by Coldstreak 

I think this song is about someone who spent his/her entire life sheltered and He brought them out into the world.

"What you want What you got Live your life in a crawlspace Help you out But you don't Want a chance at a better life You said you never took a ride And now you wanna play Well it's a big, big city Let me show you around" They spent their entire life in a "crawlspace"(sheltered) and now they want to see what it is really like

I think toward the end when he sings "I'm a wreck I'm a mess I'm a spot on the pavement I'm a number on the wall I'll make your soul tired I don't think I like this game No more"

i think he is saying he has been in the world so long that he is a bit sick of it.

So far I think you are very right on. It's about a girl who grew up sheltered and innocent and then moved to a big city. She got caught in the fast-paced, exciting, dangerous and thrilling world of the big city. She probably broke some people's hearts and made a bunch of mistakes. The crossing of the line refers to the loss of innocence. She crossed that line from sweet girl to crazy party girl and now she can't come back. She can never look at herself in the mirror the same way again...
