How these two meet
Aries and Libra: neither of you has been like this the whole time. You made each other like this.
Every decision in this house gets classified before it gets made, and the classification is the argument. Aries hears a plan. Libra hears a proposal that has not been put to the room yet.
Neither of you is being selfish and neither of you is being weak. You are holding the two ends of one question, which is whether a person is a self that joins things or a relation that a self appears inside.
Mars decides and moves, 2.13 years between reversals, no signal before the turn. Venus weighs and does not stop weighing, and never opens more than 47.3 degrees from the Sun. Both cardinal, so you both start things, in opposite directions.
And here is what an axis does that a mere difference does not: it makes both ends more extreme. Every time Aries decides alone, Libra consults more. Every time Libra consults, Aries decides faster. Neither of you has been like this the whole time. You made each other like this.
Which of you moved first, and how far did it push the other one?
For Aries, the work is putting one decision to the room before making it, and letting the answer change it.
For Libra, the work is deciding one thing alone and telling the room afterwards.
And a third: neither of you gets to say the other one started it. On an axis, both ends are always moving.
Mars decides and Venus weighs, and this is one of the six axes the wheel is actually built on. The two of you are not a pairing. You are the two ends of one question.
Neither of you can move without moving the other. That is not a metaphor about closeness. It is what an axis is.
180 degrees apart
A hundred and eighty degrees apart, straight across the wheel, and a classical aspect. Opposite signs always share a modality and a polarity: both active or both receptive, both with the same instinct about speed. Their elements are the complementary pair, fire with air or earth with water. Opposite is not another word for incompatible. It is one axis seen from its two ends, and each end can only see the other.

A sign is still a general lens: it says nothing about where your Moon or your Venus actually fell. A synastry report reads your two real birth charts against each other, with the aspects that are genuinely there.
