From my view, love spells do not create anything; they only nourish what's already there, like any other form of magic. I honestly don't believe in the effectiveness of love spells to an extreme degree. I recognize some write and cast them, but I don't believe in their effectiveness, it would be rather scary and disturbing if they were like fiction.
Love spells do come in many forms, as I believe Asatru was trying to illustrate. There are some love spells that are gentler, some for passion, commitment, friendship, etc. There are even love spells written and made as a sort of "love me or die" scenario.
They're both love spells, but are seeking different things.
