Trazamataz: Do not be foolish. Those "randomly fake things" are symbolism. Stop taking things so literally. If you would pay attention to most of their songs, none of them are literal. They way that they compose their lyrics is poetic. Obviously, you just do not understand that.
In my opinion, I don't think that it is about a lover at all. I believe that it is about a friend that he was close to and fell in love with. Then she began to change for the worse. They drifted apart until one day she came back heartbroken when someone returned to favor and used her and abused her like she did to them. And he didn't trust her manipulating little self and let her fall on her own.
