I find that South Node connection work well with friends and such, but for lovers they will hold you back.I had my 29' Aquarius south node conjunct Aquarius moons of 1 romantic partner (middle decan with Scorpio sun), 1 platonic friend (early decan with Cancer sun) and 1 parent even (1' Pisces moon with Taurus sun) indicates close relationships of family togetherness-it appears I'm closer to my mother than father going by the natal chart, helping me get by in life and my GF is someone who understood me since we're both on the autism spectrum...and I have an Aquarius sun-moon conjunction, the sun is rather closer to the SN than the moon, but I'm dealing with challenging sun signs and the closer the moon to Pisces or Capricorn in the distance of my SN, there will be obvious differences in the formation of romance, as well family feuds and maintaining a friendship with these 3 people. I will take a closer look at the other planets (their Venus conjunct my SN should be considered).
I wanna add my social worker for people with neurological disabilities in independent living has an Aquarius sun so there's not really friction and it's compatible. And another is my natal Mercury in 13' Pisces is 15' away from the SN opposite in the degrees from my sun and Moon. I have Aquarius and Pisces sun friends conjunct my SN too (2 married couples). I don't know anyone with their Mars conjunct my SN in either Aquarius or Pisces. One of the married couples has a Jupiter conjunct my SN (in its traditional sign ruler Pisces as well), but they have an Aquarius in Saturn conjunct SB (well, she was a grade school teacher for special ed students, but the Jupiter conjunct sun eases the student-teacher to later family friends over time) . The potential person's natal chart planet conjunct my personal SN (traditional planets) could determine who I should acquaint, befriend, date or marry.
Edit: My GF and the couple are early 1960s babies to both had their Chiron in Pisces conjunct my SN (GF's is closer, right on the cusp), and my late Mom's has a True Node in Pisces conjunct to my SN (opposing nodes I take it). Another married couple in my birth year 1980: their Mercury - her's conjunct Aquarius sun conjunct my SN in Aquarius, his is in Pisces, but her Venus is closer to my SN in Pisces than his which is a Pisces sun.
Edit2: My social worker has a moon within a sign from my SN and her TN is in Pisces. Is this why I got along with her so much and so well? Maybe.
