Hi, I need help with this spell. Recently a guy that I had a crush on and had been flirting with, well, I found out that he has been engaged for a while and was toying with my heart and made me believe that he loved me. I want to get back at him and make him suffer the same way he made me suffer. However there is only one problem. The spell I found, tells me I need to visualize the couple breaking up. Now even though I have seen his face, I dont know what his fiancee looks like, I only know about her name. My question is, will the spell still work even I dont know what she looks like? Or do I need to obtain a picture of her?
