When asking for help I reccomend defining what you need help with.
As in, define crush spell? (I got no idea...)
I wouldn't know what went wrong unless you were to describe the specific incantation, ritual, or whatever. Also, describe how you performed it, specific details such as time of day, day of the week, and the materials you used.
Then, I might be able to help you. If its some sort of love magic I won't help you. Screwing with peoples minds is wrong, in my opinion.
