I naively did a binding love spell last year, but I was skeptical. This guy that I really like reciprocated my feelings and it was mutual, but due to conflict of interest and being cautious about losing both our jobs, he kept things strictly professional. After we parted ways, I did the spell. After that, things got strange; I have no desire to date other guys or move on even after a year. I think about him often and the memories we shared together pains me. I miss him. And also until Now, he is strictly single. We never saw each other again and I really regret doing the spell. I did not have the courage to friend him on Facebook or visit him.
Perhaps it did backfire. But you could have potentially overlooked something when you cast the spell. Where you in a meditative state when you cast the spell? Was the spell cast correctly? Did you put enough energy into it? Even the slightest mistake can effect the outcome.
When doing spell work you need to be focused and have pure intent. If your intentions were conflict or have any hesitation then the spell could go wrong especially with love spells as they are about strong feelings and emotions.
It depends if you want him or not. Either way try a spell to clear the air and negate the spell and try again.
