There are many love spells on this site, just do a search. Personaly, I wouldn't recommend using magick for love. If it is a spell, it is not love! So, at the very least, you will feel unfulfilled. Also, such spells can lead to dangerously obsessive behviour from the subject of your magick. Have you considered what would happen if you decided you didn't want them any more, for example? You could end up with a stalker, who could damage you in various ways. You could get hurt physically.
So yes, these spells have an effect. However, if it is love you are looking for, you won't find it in magick. As another option, you could use magick to help to make yourself more confident, therefore more attractive, to the right person. We are not always the best judges of who the right person for us is. Ask yourself if you're looking more at lust?
Hope this has a good outcome for you. :)
