Since I've been drawn to threads concerning The Divine Science recently I may as well reply here too. I am a student there as well, so I would also love to establish communication with interested people where it might not otherwise happen directly with the school's teachers, since they are naturally more focused on their students than public relations.
Obviously if Prophecy (or someone else) finds the time to reply, consider whatever they say with more weight than what I say.
You do sound like you would do very well in The Divine Science. Love in its divine aspect is indeed discussed there, and eventually in a very thorough way - it is in fact one of the five central pursuits of magic as we view it - the others being Truth, Liberty, Peace, and Light. So your interest in Love is a very good thing which you can safely hold without any fear of "wasting" your time with it. From how you yourself have described Love I am particularly confident in this, because you are not identifying it with strictly erotic love (which has a part to play but which our culture tends to overemphasize).
As far as your feelings of wasting years of time - don't worry about this. Every experience we have has a part to play for us, even if we change our opinions later, because even our errors help to refine our understanding of our path. How could that not be valuable? Don't worry too much about the name that you give to your path. You can start one, switch to another, and land permanently on yet another - if you do this, you haven't really followed three different paths; YOUR path simply travelled between three places.
I do not know what the symptom you wish to change in yourself is, but I can make a recommendation. The Pentagram rituals are great, but the downfall of ritual is that they rely on certain foundations (visualization, understanding of symbolism, relationships with certain intelligences and forces) which may or may not be present in the person performing the ritual to begin with. They will certainly eventually develop if you consistently practice the ritual (I myself did the LBRP consistently for a time and observed great progress) but if you are specifically trying to heal yourself elementally, there are quite simply more direct ways to do it, like Franz Bardon's Soul Mirrors, which The Divine Science also uses. If you are unfamiliar with this, here is the practice:
1. Introspect for a long while and write down every characteristic of your personality that you can think of, positive virtues and negative vices alike. Be as thorough as possible, and keep adding to this list whenever you identify something new.
2. Separate the virtues and the vices. Naturally the vices require the most work, but you should be aware of the virtues as well for the purpose of elemental balance.
3. Get a good understanding of the elements (and try to avoid pop culture interpretations) and assign an element to each of the virtues and vices as best as you can - you can always go back and change things as your understanding deepens - this is an ongoing process.
4. Assign a degree of magnitude to each of the virtues and vices. I, for instance, assign a 5 to Distraction, which influences me constantly, but a 1 to Anger, which very rarely really struggle with.
5. You now have an elemental roadmap to your personality which you can use to more or less objectively work to improve yourself, and heal your mental and astral bodies, which will in turn improve your material life.
6. Choose a prominent vice, consider a virtue which represents the healthy functioning corresponding to the absence or conquering of that vice, and work to embody it and make it a new part of your being. Update your Mirrors regularly (maybe once a month, maybe once a year).
7. It may be useful to consider how certain vices give rise or support others, so that by healing one vice which supports many, you can accelerate the process.
Now, concerning women... obviously culture has not been kind to women due to patriarchal society and such. This same cultural idiocy unfortunately has also occurred in esotericism, with specifically fraternal orders and such existing. This inequality is completely unnecessary, and everyone would benefit from its disappearance. There is nothing precluding women from the mysteries whatsoever - but because of patriarchal bigotry, history itself has not been kind to female mystics. Study people like Moina Mathers, Helena Blavatsky, Mary the Jewess, and Hypatia of Alexandria if you'd like. In any case, if you are female, I strongly encourage you to help turn the tide by becoming a successful mystic yourself. Women actually tend to be better at metaphysical perception (which is why so many seers have been female and the whole witch stereotype exists), and this is not only tradition but has recently been supported by modern scientific inquiry and psi studies. It is only a general trend of course due to energy body differences.
Anyways, I hope this has been helpful. Don't abandon trying to contact my teachers, obviously, but if you have any other questions you think a student might be able to answer, feel free to ask me.
