This is about the anxiety a girl has over seeing her ex again after a breakup. The lyrics suggest that the breakup was a while ago (the time has shown, your hair has grown) and also that there are still residual feelings in the air but the guy had done something irreversible and unforgivable (oh, i love you some, but oh, the things you've done). In the end, both parties will "disappear in to directions" and go their own ways after this meet-up.
