Ask yourself this question... can true love be forced? Love is not a force to be reckoned with, it is so powerful that are only a few, very powerful forms of magick and spells that can even attempt to control it. Casting a spell or empathetic manipulation would be reckless without high natural ability or years of practice. Even if you were successful, could you live with yourself knowing that you had to stoop down so low to the "cesspool" of magick to make this girl love you? Please, try practical means first.
