Messing with love with magick in general is never really a good thing to do. Because sometimes things can backfire or happen the way you not intended it to happen. Its always better to let love flow naturally in a spiritual sense. Meditation can help you bring love to you if you want to find love or bring someone closer too you.
But sometimes binding someone to you can prevent them from doing any harm to yoo or keep them away. Binding spells take time and practice.
I am a big advocate for not using any love spells. It is something I will never do and I council many on wanting to use something. I generally present them with this simple statement: Why would you want to be with someone that truly does not want to be with you? You can't change someones feelings. Sometimes two people just are not destine to be together and really the soul mate is still out there undiscovered.
But people come into our lives for a reason, usually to teach us things. So don't disregard anyone. Having said that, all of the love spells, binding spells or spells of that nature that I have known to have been cast, all have failed. The end result is generally the same, the individual that it was cast on develops a hatred or distaste towards the person casting it. I have even spoken to someone I knew another had cast a spell on and they simply told me they had no reason or explanation as to why they started feeling this way but the simple thought of the girl revolted them. It is heartbreaking because it has ended friendships that could have remained.
Just use caution when trying to change free will. I never recommend it. Instead I will suggest a honey jar spell or friendship spell to help warm someone up to you.
