Binding love spells can be tempting, but you should think about the possible consequences of using witchcraft and magic to make someone love you.
It's not always easy to see where the fine line is between white magic love spells and black magic love spells, and even then there are various levels of manipulation you may be attempting. While black magic really just refers to a spell that targets a specific person, binding love spells are ones where you actually force them to love you. You can cast a spell towards a certain person that doesn't cross that line to force them to love you.
Using a spell to get someone's attention, or to improve your chances is one thing which I personally don't have an ethical problem with. But when you try to force the issue and create an emotional bond that isn't naturally there, you're asking for trouble.
Most witches would say that this kind of magick is wrong because you're messing with someone's free will, which makes it morally wrong. Not only is it wrong but will ultimately be unsuccessful since you can't really keep casting spells forever to keep the "love" intact. Another possible problem is that you may find out you don't really want this person after all, and then have problems breaking it off because of your magick. Do you really want to end up with a hostile stalker? It's just not a great idea for many reasons. I don't recommend it.
The safer and more generally accepted way of casting love spells is to keep them generic, and just let the magic find the right person for you. Sort of like setting up a magnet to attract someone to you. You can find many free love spells online that fit the bill.
Though it's tempting (very tempting) to use magic and witchcraft to get exactly what you want in love, please take some time to honestly consider the consequences of your actions.
