You said you loved me in the back of a taxi You swore that this was bound to last I thought you meant it, but then you got sober And you said you don't remember that But I remember that I heard that you're living in that same old house with no AC And still driving your ex's car I heard that you haven't changed You're still stuck in your same old ways Just breaking someone else's heart I'm so stupid happy that you left Like who are you? And if you see me having fun It's all cause you're my ex Like who are you? So I'm the late night, still turning to daylight With you not picking up the phone You called on my birthday And said that you're clean now But you know that I know how it goes I'm not going down that road I heard that you're living in that same old house with no AC And still driving your ex's car I heard that you haven't changed You're still stuck in your same old ways Just breaking someone else's heart I'm so stupid happy that you left Like who are you? And if you see me having fun It's all cause you're my ex Like who are you? And I'm having the best night, best night here without you The best night, best night here without you The best night, best night here without you Like who are you? I'm so stupid happy you're my ex Like who are you? I bet you thought you really broke me I bet your ego lost our story Sorry to break it down but when you're not around It just gets better and better I'm so stupid happy that you left Like who are you? And if you see me having fun It's all cause you're my ex Like who are you? And I'm having the best night, best night here without you The best night, best night here without you The best night, best night here without you Like who are you? I'm so stupid happy you're my ex Like who are you?
