Separating planets in astrology synastry

So far I have only shared what brings us together in Synastry and compatibility in astrology charts. You can see those videos on my Youtube channel. In this video I talk about the 3 planets that cause separation in relationships, Sun, Saturn and Ketu.
I use Sidereal zodiac. Use Cosmic Insight app to see where your planets are.
I realised I mentioned Rahu separates but actually I meant that the Sun separates, it is too much of an independent planet to work with others.
