I think dorareever is right in a sense: this song does have something to do with a troubled relationship, but I don't know if it's as blatant as the narrator's lover being a cheat. I think there's some suspicion there, but ultimately it's about two people on opposite ends of a spectrum and the narrator's realization that the only way to make things work with this particular person is to give in to what she expects, for better or for worse (probably worse). "I'll get through becoming you" pretty much spells this out, and "bottle up and explode" means just that -- keeping your frustrations inside until you blow a gasket, kind of like "red, white and blue" fireworks.
