If You Were Here

The song stars and ends with wondering what would happen "If you were here," presumably meaning that the person to whom the song is directed isn't present. I think the speaker went through a typically difficult breakup of a relationship--something, it appears, that has happened before ("I'll be always falling")--and is now trying to emotionally cope with the fact that another relationship has failed by painting it as something (like all the others) that never really mattered in the first place. Essentially, "If you were here I could tell you how much I don't like this relationship either and how unimportant it is to me, too." The person to whom the song is addressed, however, isn't there anymore--he or she is already gone. So the song thus becomes a self-address and a reflection on how this type of thing always happens--the speaker has these breakups and then puts up the wall of "I was never emotionally invested so it doesn't matter." At the same time, however, the speaker realizes that this part of his or her life will be always broken (cracked). He or she will spend time on songs like this which help to "repair" the pain of breaking up with someone by making it sound like no big deal, but the speaker realizes that "Just like the rain, I'll be always falling, yeah / Only to rise and fall again." I think, therefore, the final "Do not want a part of this anymore" isn't about not wanting to be in the original relationship that the first "Do not want a part of this anymore" refers to, but rather is a statement by the speaker that he or she doesn't want to go through this process of pretending not to be invested anymore.
