It must be love 'cause I miss you more Than myself on days when I can't get up It's clear that I have nothing figured out But theres a spark still in my mind And I knew that it was you this whole time It must be love because it's killing me and still keeping me alive I heard it takes 15-17 months to get over and forget the pain Or it takes twice the time it took to live through in the first place And so I grit my teeth and bear it I know theres no better way It's a fact and its been proven time is the only escape It must be love because it's teaching me to hate What was I thinking What was I thinking What was I thinking when I gave you I gave you my heart What were you thinking What were you thinking What were you thinking when you tore it apart I heard you got a new girl but i'm not too worried In fact i'm confident that history will always repeat And all your nervous ticks and quirkiness will surface sometime soon And over coffee we'll agree the problem was with you It must be love because we couldnt see the truth What was I thinking What was I thinking What was I thinking when I gave you I gave you my heart What were you thinking What were you thinking What were you thinking when you tore it apart Your hopeless light is still haunting me Like there was good hiding somewhere underneath I know better than to let time get the best of me The best of me What was I thinking What was I thinking What was I thinking when I gave you I gave you my heart What were you thinking What were you thinking What were you thinking when you tore it apart
