Have a look here: Reconnecting with the ex??
And some other threads…
I’m not saying that you wont get a fling out of it, but turning an ex around will likely take more attention and time than one party. The party may serve to reignite some flame or make her jealous, but I don’t know an ex (mine or otherwise) who will go right back to you. That combo should suffice to that end, I would be wary about over scenting. As to diffusion points, I would put the ammo and IS on your neck and the IH on your forearms.
