I’m having a hard time putting thoughts together cohesively at the moment but I’ll do my best to explain.
I don’t believe in making something from nothing when it comes to love magick. Which is why there has to be something there to begin with. If the target doesn’t have any kind of romantic or physical attraction to the caster, then it’s likely that a single love spell is going to fall completely flat, as magic tends to follow the path of least resistance. If there nothing there to build on and excite into genuine love, then the exercise is all but pointless.
If there is lust, attraction, even passing interest; the odds shift slightly. The challenge then is to skilfully and with great precision manipulate odds in your favour so that tiny spark has a chance to become a brighter flame. Even enmity has a chance of being manipulated into love. But to go from indifference to “I would die for you” is not an overnight change. It’s not out of the realm of possibility by any means, but it relies on a hundred different shifting variables coming into perfect alignment. And this kind of love I’m talking about, romantic love, is a two-way street. Some people do aim to go from indifference or disinterest to this level of “I’d die for you” love, but that tends to target the outcome not of love, but of obsession.
So, I believe it would require much more skill and subtlety to turn a stranger seen from afar into a spouse than it would to open an existing channel between two people, no matter how tenuous or combative the emotional connection, to let them see the best in each other, and to excite those hormones and pheromones and thoughts to just the right level that love and commitment becomes likely. You can guide it, shape it, cajole it, nurture it, but you cannot compel love — only obsession, which can be dangerous; or slavery, which would quickly become tiresome and repulsive, as the qualities of the person you thought worthy of your love spell become subsumed by a slavish desire to please you at any cost to themselves.
True unconditional love is not something I think can be compelled. It must be organic, but the circumstances have to line up precisely to birth that possibility, and from there it can be nudged in the right direction.
The reason I don’t think of love magick as compulsion necessarily is because any compelling force is extremely likely to negate the two-way aspect of “true” romantic love, as above. Either it becomes obsessive or abusive as the other seeks to absorb and possess you entirely, or it becomes hollow and meaningless as they negate all aspects of themsleves to fit into the mould you provide them.
Also, whether it can be said to fit into the above mindframe or not, I generally operate under the paradigm that creation is finished, time is simultaneous, and we live in an ever-changing soup of potentiality which shifts based on the operant power’s attention. Something akin to multisolipsism and the many-worlds theory, or something. In this timeline I cast a love spell which works; but there are uncounted other timelines where it doesn’t work out. Since each of us exists in this superimposed state, am I compelling someone else against their will? Or am I simply consciously selecting the timeline where circumstances managed to align perfectly so that love is possible?
Hopefully at least a sliver of that made some sense
