In addition, I have the absolute worst luck at dating and relationships. I can never seem to form a long-term partnership because I "come on too strong" and feel very deeply, which scares a lot of people away. That's the main reason. Other times, people would give the most ludicrous and irrational excuses not to pursue me after the first date (which usually goes very well!), most likely because they feel so insecure about themselves when they come into contact with my energy. Every time I get rejected or tossed aside for no logical reason, I then lash out at them with most hateful and hurtful words nobody has ever heard someone say to them before. I do that in order to give a "crushing blow"...to make believe that they're dead to me so I can move on.
Because of these irrational excuses people tend to give, I'm really beginning to think that these failed dating attempts are karmic in nature, due to a past life of committing suicide.
Based on looking at your chart, I think these relationship issues are all about your current life. Maybe there are also karmic elements involved, but that may be a subject for another post, since what I have to say here could be lengthy....
I have a similar chart to yours in some ways: I also have Capricorn rising, the sun, Venus, and Mercury in the eighth house, Neptune in Sag (for me, Neptune is in the eleventh house instead of the twelfth, but it's near the twelfth house cusp and conjuncts the moon, which is in the twelfth), and where you have a square between the sun and Neptune, I have a direct square between the sun and the nodes. And, like you, Saturn, the ruler of Capricorn and ruler of us Cap risings' charts, is the only planet I have in a water sign.
In a
thread I posted about Saturn in my chart, someone told me this, and it could easily apply to you, too:
Saturn is where we feel our separateness from life most acutely, but this separateness is really a figment of the imagination, and Saturn's ultimate purpose is to show us the futility of trying to compensate for this sense of separateness. Since you have Capricorn rising, the Saturnian process (of realising the futility of seeking worldly compensations for an illusory sense of separateness) has great bearing on your ability to emerge spontaneously into life moment by moment. The way that you engage with the world around you will be inhibited by Saturn problems (such as self-doubt, frustration and over-compensatory ambitions an cynicism) to the extent that you still believe yourself to be separate from life, and thus inherently insufficient.
Looking more closely at Saturn's placement in your chart, it is the only planet in a water sign. So the sense of separateness arises on the level of feeling. The process described above will draw you into water-type insecurities. You won't necessarily be especially aware of these insecurities, because the fire earth emphasis in your chart confers on you the luxury of generally avoiding the fact that feeling intimacy is very important to you deep down. But they are there waiting to be looked at.
Only difference here is, you have more of an air sign and perhaps slightly less of an earth emphasis than I do, but we both have fire emphasized, and we both have fire sign grand trines. Yours links the moon, Neptune, and your Venus/Mars conjunction. Since you have Mars and Aries involved in your trine, plus the very independent Capricorn rising and Saturn conjunct the MC, it's no wonder that you come on strong, and no wonder that you have a very fiery and militant way of reacting and covering up your emotions. (I tend to coldly withdraw instead when I feel hurt by someone, maybe a difference in our Saturn placements--mine is in the seventh house, in Cancer.)
Furthermore, Scorpio is well known for its sting. You have Saturn in Scorpio plus a significant concentration, including your sun, in the eighth house, which would give you some very Scorpio-like characteristics even if your chart's Scorpio were empty. And compounding that further, your Scorpio Saturn is conjunct your Libra Pluto... Libra, relationships; Pluto, ruler of Scorpio! Your description of lashing out at exes with horrible, hateful words fits the picture perfectly.
Having Cancer descending indicates lots of feeling in the realm of relationships, and a need for a sensitive and nurturing partner. The sun in Libra indicates a core personality's need to seek balance and harmony in everything, including but not limited to human relationships... and this need comes, paradoxically, from not having enough balance and harmony to feel secure. And your sun is on the cusp of Virgo, so would be somewhat influenced by Virgo's need to develop through being useful to others. Very likely, that results in placing some extra emphasis on the relationships arena of Libra.
It will take another post or two, I think, to explore what this would mean for your karmic growth. Will close for now.
