I guess it's what we learned about in physics It must have been in classes I was skipping Every action has an opposite reaction And we were just two opposites attracted I wish I never gave that ultimatum Showed me all your cards and then you played them I know I kinda hate the way I hacked it But I still resent you for reacting We never really could see eye-to-eye Good for you was bound to be goodbye Why is it so easy for you to be happy when you leave me? No, I kinda wanna say I'm sorry But it doesn't feel right when you're out of my life Why are you so okay? Kinda hoped that you would end up lonely Drinking on your own and then you'd call me up And I'd say, what the ***? They say that if you love it, set it free But if you kinda hate it, then you leave I guess it's just the way it's gotta be So tell me if it's all infatuation And tell me why my stupid heart is breaking Chocking up a problem's just some growing pain Side effects of exes, babe Why is it so easy for you to be happy when you leave me? No, I kinda wanna say I'm sorry But it doesn't feel right when you're out of my life Why are you so okay? Kinda hoped that you would end up lonely Drinking on your own and then you'd call me up And I'd say, what the ***? Why is it so easy? Yeah, I wanna say I'm sorry But it doesn't feel right when you're out of my life Why are you so okay? Kinda hoped that you would end up lonely Drinking on your own and then you'd call me up And I'd say, what the ***? Why is it so easy? Yeah, I wanna say I'm sorry But it doesn't feel right when you're out of my life Why are you so okay?
