I think it’s totally different. Changing a mental opinion, such as, which job candidate is best, that is more fact based is one thing, it may not really matter to the person either way, so if they change their mind… they don’t mind.
Now with emotions you are not just affecting a neutral mental opinion, and if they have strong feelings about their opinion mind control spells have the exact same issues, you have two bodies to affect, mental and emotional and the deep interaction those have with the whole gestalt.
So the emotional body involvement is an additional and critical interconnected element, because your mind has opinions about how you feel and you have feelings about your opinions. And it gets more meta than that too. You have two areas to influence, so if people target just the emotions without factoring in that the person will have meta feelings about why they feel certain ways, and meta meta feelings and opinions about that and so on, it gets complicated and the target is missed.
At the easy level, it’s a case of, "yeah he still turns me on, so what, he’s bad for me and I respect myself more than to get back with that jerk, I’ll et over it" or “huh, I don’t get why I like them, this is weird”. I don’t know about guys, but “weird” is enough to make most women take a step back, evolution has made us very, very cautious.
Now add the idea that their feelings aren’t just an opinion of their thought, but tied up in their very identity. E.g., the "make a straight guy gay for me" spells, but no less devastating to a person that has rejected someone for reasons that include identify values. Examples of this are “I don’t deserve to be treated that way” bad history or “but they’re not my type”".
Then a spell to force a change here can really start stirring up a “dark night of the soul” as a man questions his orientation, a person hates herself for wanting a dude she perceived as treating her badly (“he dd xyz, I must hate myself to want them back”) In this case the feelings can turn inward to self hate as the target perceives that they are their own worst enemy and seek distractions and distance to work though it.
Or it might simply be an easier case of, the spell makes them think of the person, but too many memories of fights and the bad things said reminds them why it’s a bad idea and makes them feel bad again. This person cuts off contact just to get more peace of mind.
So, when you start affecting the emotional body you’re hitting deep psychological pieces that touch many areas, interconnecting with values, experiences, memories, the feelings about all those, and who they even are as a person.
If the spell doesn’t help them forget the mad, bad and sad times, help them forgive, feel safe again, AS WELL as just desire, it’s probably going nowhere at best, and into annihilation land at worst.
If there’s burned bridges, try to fix those or there’s no way to cross the divide.
if there’s no burned bridges and it’s to create attraction where there was none, work on mental persuasion of suitability in tandem. (But be able to follow through and deliver for it to work, glamour doesn’t overcome bald facts.)
