On My Sonar Songtext

i feel so stupid after all
its all so strange what could be wrong?
you're gone but still you're on my sonar
there has to be some huge mistake
what girl in her right mind would take
this boy for granted, you're on my sonar
what could be so perfect won't
& you could love me but you don't
i'm separated from you now
i can't believe this tell me how
