I believe this song is about a guy who keeps saying he wants to be with her, but then decides he doesn't, and so on. Hence the line "Got a case of the love bipolar" and she continues to go back to him everytime he says he wants her back, no matter how much the breaking up happens. Such as the lines "Stuck on a rollercoaster,Can't get off this ride" and "We fight, we break up, We kiss, we make up"
