I Didn't Understand lyrics

Thought you'd be looking for the next in line to love Then ignore, put out, and put away And so you'd soon be leaving me alone like I'm supposed to be Tonight, tomorrow, and every day There's nothing here that you'll miss I can guarantee you this is a cloud of smoke Trying to occupy space What a fucking joke What a fucking joke I waited for a bus to separate the both of us And take me off, far away from you 'Cos my feelings never change a bit I always feel like shit I don't know why, I guess that I just do You once talked to me about love And you painted pictures of a never never land And I could have gone to that place But I didn't understand I didn't understand I didn't understand
