Green Fairy -Those were silly?
THIS is silly ...
I'm wondering something about having all those Planets in the other's 7th House, maybe cz I'm a Libra Sun and I have no Planets in my Natal 7th ...
... If someone had all those Planets in MY 7th, I wonder to what Degree that would affect OR ACTIVATE my Libra Sun. You have a good question, and wow ... if you guys have those "double whammies(?)" with your 8th House Synastry, I would think there would be a good understanding between you with 8th House issues, like money and power, including power over others. You might feel like you're on the same page.
Two "money planets" are Mars & Saturn, and if their's are in your 7th, I'm thinking there is a huge emphasis on money issues. Mars is very action-oriented and can be quite hot about direction. Saturn can be thought of as the Goat who not only climbs up the mountain slowly but surely, but also digs it's heels in the mountain if you try to pull them down.
Is it a romantic relationship? I'd love to know what your Vertex' are doing in Synastry cuz if there's a strong bond there it might be inescapable.
