Can Separation still be used if you suspect a 3rd party but you don't know the identity of that person?

He’s currently not with you so it’s only harming what’s around him.

This sounds awful but I was wondering could you chant to ruin all romantic relationships he has except for you? I say in the booklet that it said "dont say things you dont want" but I dont know hoe to properly word that without it removing me too ya know? I just wanna be the only one he does has a relationship with 😅

Yes I have done it that way with only my targets name and had complete success.
