Sure I did. Not for me, I could never quite be bothered to try to change the mind of a guy who didn't like me, though to be perfectly honest, it's not because of all those real deep moral things about manipulation you've said before; it's just a lot of hassle for spells that have such an unstable result, me think, however, my best friend really liked a guy who was single, so we cast a spell for him to look at her in a new light -and put plenty of love related ingredients to influence that new light he was meant to see her in.
It kind of worked, he did become attracted to her, and he did ask her out, but it didn't make him any less of a cheating a**hole than he'd been with all his other girlfriends before, and it all ended up with a great brilliant knee in the balls and a crepe and nutella therapy.
I do however love to take Love baths, not the one from before, which seems to be an actual spell but its pyaye, or, call it Condomble, Voodoo, Santeria, whichever, it's dedicated to Erzuli Freda, the loa of love and lust, and it's a great moral and awesomness booster, you either buy or make bath salts out of her plants of predilection, soak in well and take good care of your body, thanking her before and after for her blessings, after which I personally use her appointed scent -Florida water, and draw her veve on my skin with glitter khol. I always feel more confident afterwards, and if it's a party I usually get a guy by the end of the first hour.
Maybe it's just because I feel so much more confident afterwards. But maybe it's magic.
