First off, you should not use love spells to make people fall in love with you, or anybody else. They do work, but not the way most people would like. Most of the time, the person you use it on, just follows you around like a lost puppy. They are not able to think for themselves any longer. you should never use them.
Secondly, spells take time to work. You can not speed them up. It can not be done. If you are going to do these spells, you need to wait. You must have patience with magick in general. Not just love spells, but all aspects of magick.
If you are looking for a way to just snap your fingers right after the spell is done to have it work, you are sadly mistaken my friend.
