Does that mean we are not supposed to be together in this life time? :( I am done being in relationships that has no future. :(
Sometimes you have to risk being vulnerable in a relationship and it's okay you aren't coming together this time around . It's not his or your fault.
If you fee a strong pull towards a person that can by itself say a lot.
Do north nodes really define strong karmic influences ? Yes.
Are they the only one factor that define strong influences or how two people might get along ? No
A strong karmic partner can have various other astrological influences on your chart. What you have just mentioned can also be an indicator of that.
I do not have my nodes in sync with so many close people in my life. It is not the only indicator. You can define how an aspect can work along with another in a chart, but it is not the only one. According to me what your original question was, it is an shows of a partnership where this growth. But the equation might not be the same as isolation solely of one aspect alone and comparing it. If you know what I mean. There are various ways you can look at synastry, what you just mentioned is one of the ways to look at it.
Astrology can be helpful when it comes to relationship compatibility, but it's a lot of things. And it is the whole picture.
If you are applying other divination tools like Tarot/ Runes, the outcome could be different. Unless someone sees your whole chart, they really do not know in astrology sense.
