As Thoreau- worlds first Happy once said "things don't change, only you can." get over him/her. there will be a better one coming along. If they 'duped' you then they are certainly not good enough for you and you deserve better.
If you mean bring back as in back from the dead, well, no. It wont. If you mean bring back as in bring back to you, well, still I don't believe it will but if your loved one believes in voodoo and knows of the spell, the power of suggestion may make him or her come back. But why try to bring back someone who duped you? Show them that you are too good to settle for that type of treatment!!! A lot of times that attitude will make them realize that it was their loss, not yours, and that can be a very attractive thing.
Don't play with voodoo. Thats the dark magic. The magic that harms others.
Now, one thing you need to realize is that magi ck doesn't have the power you seem to think it does. It can't force one person to love or hate another. If that loved one is gone, then they're gone and you need to leave it be.
If you love someone, set them free. If they come back to you, they're yours. If they don't, they never were.
