Love spells can backfire on the caster so I wouldn't advise you to cast one on anyone. If you are looking for a spell to draw love into your life that is different and should be fine, as long as you're not trying to lure in a particular individual.
Most of the spells on the site don't work. You're best bet would be to write and cast one of your own. The chances of it working are far greater when you do so.
