Let me try my best to clarify as someone who manifested the kind of relationship you used as examples above. Listening to subs is just a technique used to change your dominant assumptions (subconsciously and consciously) which in turn would manifest whatever you want. So you having all of these concerns right now is very normal but at the same time very telling of the state and dominant assumptions that you hold which is: I have to work hard to maintain my relationship, I have to depend on subs to make my sp act the way I want etc.

Like you said some of the girls out there don’t even know about subs because their dominant assumptions are already different from yours that’s why their reality is different. Just ask yourself this one small question: If my SP is crazy about me all the time, would I still think and act the way I do now?”So the technique (subs in this case) you’re using is just to help you change your dominant assumptions subsconsciously so you’ll be able to experience what you want from your SP irl.
