My classifications will not be your classifications, I agree that Saturn is certainly more fitting for controlling behaviour, your issue is not just one issue but stems from several. Working on these issues, these socialisations, and self-created demons are a life-long work and won't be remedied by one ritual. It takes work and you would perform several rituals after doing further work after each one. That is a wordy explanation, I can only tell you what my approach is with this ritual. Jealousy in love stems from Venus for me because of personal work I have experienced regarding Venus, also my love life is different to your love life. I also see it as stemming from Netzach in general. But my qabalah is not your qabalah, the tree of life isn't universal, it is a glyph which you map your own experiences on to over time.
The associations will only work if your mind speaks those associations or has learned its own language. That is the whole reason for correspondences that we have a language the unconscious can speak. Reading a good astrology primer will help you with these correspondences, as will mythology.
I would identify a problem in my life as expressed by an unhealthy behaviour. I analyse this problem and get to the root of that issue, where does it stem from? When can I first remember feeling that way? What memories pop up as associations? After a lengthy time of doing this I can normally identify at least one factor, but more often than not I can identify multiple.
I then see which ones are bigger factors and which ones are factors by association. So if your controlling behavior is really a symptom of your jealous nature (It may not be, I wouldn't know because I don't know your mind). It is, therefore, logical to tackle the jealousy first, then the controlling later. There's no point pulling the leaves of a weed and allowing the root to remain.
If you are a newbie to ritual, perhaps it would be best to first learn more about general techniques first before you start messing with your psyche? Simply by meditating on your issues, keeping a journal, and practicing regular hygiene rituals, you will probably see a difference over time. Meditation is also overlooked, the ability to still your mind and gently push aside intrusive thoughts is so helpful and can be introduced into everyday life over time.
I can't comment on other people's journies, but I will say that I have come to the realisation that a lot of my own issues stemmed from various fears, meditating on this fear and exploring it has helped me a thousand-fold. In fact, I would say once I started taking the Great Work seriously the first 3 years of my work was working through my own stuff. I found the LBRP helped, I found that meditation helped, i found that specifically meditating on fear helped, and Jim's ritual helped. However, the ritual was only useful once I understood what the problem was and put in the work to unravel it. This particular ritual, for me, was simply a way of aligning my own unconscious forces with what my conscious Self perceived as the Will at that time. It is a way of ensuring that part of yourself which you have no control over is aware of what you want and is not working against you out of habit.
Again, just my thoughts, others will disagree.
Above all,
Do what thou wilt shall be the whole of the Law.
