I hate that spell. I have studied it and have talked to people who used it. The outcome is never good. Either the target of the spell stays tormented for an insane amount of time, or they come back and (since it isn't a true love but a conjured one) the person who cast it decides to move on and sends the target back into torment. I have even heard of it backfiring where it worked on the target, making them come back, but the caster ended up experiencing the exact opposite. The caster was tormented spiritually every time their intended love was around, which meant that one of them will always be tortured.
I advise to find love without using magick to bring someone to you but to guide you to who you need to be with. This way, the love is honest, and not something fabricated through spells.
On another note; if you are set on doing this spell, make sure you have a way to remove it fast just in case it backfires or it works and you end up wanting to leave.
