Cover art for Someone's in the Wolf lyrics by Queens of the Stone Age

Homme is referring to a lost love, that succumbed to drug use probably or something that was swaying her so strongly (stronger than he) and in the wrong direction. Maybe another man who seemed to care but ultimately was simply using her, drugging her, exploiting her naivety, fucking her. Eventually she isn’t in control (addicted) and this ‘way’ finds her whether she wants it to or not. So glad you could stay forever is straight sarcasm...bitter that she used to say shit like forever referring to him, only to not be and fast. He’s warning her of the slippery slope she’s choose and the man that put her there. Boom.
