İ have some experience in this subject.
At first, your success depends on the target's psychology. When you do this to a weaker individual, your success rate will be high, not to mention your own power I think you already know this.
My goal was the same as yours:
1. I wanted her to approach me.
2. I even expected her to tell me that she loves me.
Of course, I didn’t include the second part in my spell because it wouldn’t be a love spell then it would be forcing. We were working for the same company, so we saw each other every day, which is another requirement for success.
A few days after working on this, she started to act differently. She couldn’t take her eyes off me, etc. Energy works in interesting ways people near me started calling her to help with work for no reason, so the energy drew her to me. After a few days of love work, she approached me every day and talked about random things. She also started to dress better and was drawn to me daily.
However, no serious approaches happened, far from my expectations, honestly. I expected her to approach me and tell me she loves me. The spell was clearly successful, but the target may approach you in other ways. It is nearly impossible to make the target confess their love with only using love spell, especially if the spell you’re sending is directed at a female. If you want to make that happen, you might want to add some additions to your spell because a love spell alone most probably won’t achieve that.
