ok, so.. just out of curiousity.. not sure if it has any connection or not but here goes.. if the south node represents karma and possibly a past life.. whatever sign that falls into.. could that possibly mean that person feels at home with and comfortable,yet dragged down or "held back" in some way by that sign and or, people with that sun sign? for example.. my north node is capricorn and south node is cancer.. and my rising sign is also capricorn.. so my 6th house cusp is cancer.. and weirdly I have always felt odd around cancers.. in some cases its dislike.. not always.. but it is mainly with cancer.. just an uneasy feeling.. maybe rivalry or something. Is it possible that it is a deep seeded feeling of a struggle regarding a past life or a need to be more "capricorn" then "cancer"? I have also noticed I mainly have relationships with capricorns. Im not attracted to them but it seems right and grounding.. could that be an attempt to attain the qualities of my capricorn north node subconciously through partnerships? any thoughts would be great.
Post your chart! A really important factor here is where your Moon is (ruler of Cancer). If Cancer is your 6th house cusp, that means Cancer suns fall in your 6th house, and that can be an uncomfortable placement. I would like to give you a better answer if you would like to post your chart.
I have a similar feeling as you. My SN is in Libra in the 6th house, NN in Aries in the 12th (what makes this more complicated is that I have a Sun/Moon opposition that squares the nodal axis from Cancer/Capricorn). Libra is on my 6th house cusp, and I have no planets in that sign or in Aries.
I also feel uneasy around Librans, but also drawn to them. Many significant people in my life have Libra sun or other personal planets, including my father who has a Libra Moon, my best childhood friend, my first boyfriend (also Libra Moon), both my siblings (Libra Suns), three friends in high school and college (one of which I went into business with for a while) whom had Libra Suns, Moons, and Venus or combinations of them, and my first roommate in college who has Libra sun. Notice all the "firsts" here.
In all these relationships, they are important to me but uncomfortable, strained or a growing experience. My father and I love each other very much but rarely see each other and haven't been in close contact since I was 7 years old, siblings are much older than me and we have distant relationships, my first boyfriend turned out to be gay and that was an emotional roller coaster (and another feeling of being inexplicably separated/distant), my childhood best friend always made be feel insecure and jealous, one of my high school friends tried to assault me while he was drunk and I lost that friendship because of that, I went to my other Libra friend (who I was in business with) for help when this happened and she dismissed me, and I've never been able to trust her since and my first roommate was distant and cold, like I was living with a ghost (she made me worry after she emerged from her room after not seeing her for a week, tried to make a sandwich, and collapsed on the floor while I was trying to talk to her because she was sick and hadn't been eating... I think that was the only time I'd ever physically touched her in the two years we'd been living together because she didn't like touching people... she didn't even hug me goodbye when she moved out with only 3 days notice...
).
In sum, people with Libra placements have given me a lot of grief over the years, and I think the 6th house has a LOT to do with that, along with the SN and Sun/Moon midpoint conjunction.
I have always sensed in my Libra type relationships a kind of emotional distance that makes me very uneasy. And it seems odd because Libra is the sign of "partnerships" and it always feels like those partnerships are fated but torn apart or also fated
not the be the way I'd hope they could be. Thinking of NN in Aries, the sign of independence (in the 12th house of solitude), this comes into a different light. Congenial Libra is not really there for me, or at least that seems to be how things always play out with them, and I have to stand on my own. And in that way, Libra is uncomfortable.
