you mean this spell? http://www.spellsofmagic.com/spells/love_spells/relationship_spells/12741/page.html
it should work. couple little things makes me wonder like cutting yourself with your boline. the boline is used to cut ribbon and/or herbs, not yourself. also the inverted pentagram why? it's a symbol, but why does it matter if it's inverted or not?
anyway, it does sound like a plausible spell that should work. i would also suggest trying to talk to the person, to aid in the spells effect.
of course i've got to wag my finger and tell you not to cast love spells because they toy with free will. it's a personal preference, i understand, just think before you cast, and be careful what you wish for, spells can backfire or bring about changes you didn't want, and loves spells can be the worst. so just think before you do anything.
