Incompatible couples.

Has anyone ever seen 2 completely astrologically incompatible people make it the long haul? Not just incompatible sun signs, I'm talking an entire incompatible chart!

Just curious.

no, I haven't, but you have to run a composite chart to find out
Uranus conj Sun, conj Venus, square Mars? no.
check if there's Saturn (that's good except for Venus sq Saturn), check so that there isn't too much Neptune linked to natal planets, check so that there's no violence (Mars Pluto, or Mars sq Sun, sq Moon, these are hard on a couple

they describe different facets of reality, the first is how and what you attract in each other, the second determines how the relationship will go if the two individuals interact

Eh. My parents are a Gemini-Libra couple

Venus in Taurus and Venus in Gemini incompatible.

Third decan Aries sun and first decan taurus sun not that compatible after all.

First decan Taurus female and Taurus/Gemini cusp male weird
