To me, the song is about this girl who loves a guy who is leavin her. she loves him & doesnt want him to leave her, so she wants him to take her with him bcuz if he doesnt then its over between them. but in the end, he does leave & she's still sad & hurt, but acts as if she's ok. so she wants him to be hurt & miss her when he's with other girls & when he hears that she's okay. but she still loves him, & still doesnt understand why he didnt take her along.
