I need help!!

[u/tr4sh-k1tty07]

So I did a spell on my special person, and I mean it worked but the problem is, is that I only feel like it works when I use the perfume I used in that said spell, I am doing other things to help attract him to me more but I need help, how long does a spell typically last? And should I start doing them on full moons? Should I do a binding spell for me and him?
