I think this song is about a guy who's emotionally unstable at the moment for a relationship (maybe is on the rebound). She's desperately in love w/ him and wants to "save" him from his sadness. He sees her compassion but knows he can't be w/ her right now and doesn't want to even try b/c he knows he's not ready...hence "he can't wait around while she gets blown apart."
