Wilpower as a very essence of magick is not to be abused. Unless it is your own!
Do not use spells to change the will of someone you love, that is not love.
Be careful of how you imagine the love you want while performing a spell and in my belief even after that. Do not force your love on someone, merely wish for it to be unconditional and not limiting to what you in the deepest of your heart believe to be for that person. They will love you if they are free
So far in my very limited research i have found out that the honeyjar spell is most suitable, as it does not necessary impact the freewill of others, but their thoughts about you. Which is not to say that you will not impact her will, but strive for the effect on it to be minimal.
More importantly do not abuse the effects of this spell, as in taking selfish advantage of someone's feelings.
Do not obsess over her, the spell will backfire.
I've read that it's most suitable for repairing relationships as opposed to starting them, but i do suppose your thoughts and intentions during casting and after play the bigger role.
Make sure your better judgement is not clouded by your emotions, have patience and do not haste!
Otherwise you will repeat the same mistakes as me and i do not wish that for anyone, be as it may that they give a valuble lesson to learn.
Friendship is the best foundation for love, so do not rush inbetween stages.
You are your own person, with your own challanges that you need to face alone, never forget that and do not believe that someone else may fix your reality, love is a boost, not a solution, be carefull not to overthing and forget other important matters in your life. Have luck and power of spirit!
And wait for more feedback before you do anything!
