Or, you could ignore/reject them and let it pass, and after a little while they will fall back out of love. So you are not automatically stuck with the person forever just because you used a potion on them once.
BUT would you use a love potion on anyone?
There have always been ethical concerns with the idea of LOVE potions.
If you happened to get access to a high-quality love potion for free, and could not sell it, would you use it?
Why or why not?
