How these two meet
The two of you have the best year of anybody you know, every year, and it is a different year each time.
Nothing carries over. Neither of you has experienced that as a complaint yet.
Libra starts things, constantly and beautifully. Sagittarius takes what is started and opens it wider, which is a form of agreement that also stops it being the same thing.
Between a cardinal sign and a mutable one there is no fixed modality anywhere. Nothing in this house is load bearing, and you have both experienced that as freedom.
Venus never gets more than 47.3 degrees from the Sun and never initiates the separation: it leads or it follows. Jupiter needs 11.85 years to cross the wheel and revises for a third of them. One of you keeps the room level and the other keeps making the room bigger.
Which is a marvellous eight years, and then a strange question at the end of them about what any of it was for.
For Libra, the work is choosing one thing to be permanent and saying so, knowing that it makes the other options worse.
For Sagittarius, the work is leaving something exactly the size that it already is.
The question
Where were the two of you going, before it became this?
One conscious action
one thing, made permanent
Pick one thing between you and declare it settled. Not for now. Settled.
Neither of you may improve it, widen it, or keep the alternative open. You will both find that harder than it sounds.
Venus keeps it level and Jupiter keeps it large, and there is nothing in this house whose job is to still be here.
So what have the two of you got that either of you could point at?
