Why it’s easy
Libra and Sagittarius are two signs apart, an angle called a sextile, which is usually read as friendly and helpful. Both are sociable and optimistic, and both like ideas. Libra brings style and a feel for people, and Sagittarius brings humor and a taste for something new. They can talk for hours and enjoy each other’s friends.
There’s a bit of mutual education, too. Libra picks up some nerve, and Sagittarius picks up some manners.
Where it can slip
The classic scene: Sagittarius says something blunt, Libra is hurt and doesn’t say so, and then everyone goes out to dinner. Because the mood is usually so good, neither wants to spoil it, so small things build up. Libra wants a partner who’s really present, and may feel lonely when Sagittarius is off on the next adventure. Sagittarius may feel Libra’s need for a decision on “us” is a bit of a weight.
What helps
Ask Libra what they really think, and wait. Ask Sagittarius how they’d like to spend the next year together, and listen for a real answer. You’re both more up for this sort of honesty than you might expect. Plan trips where you both get a say, since Sagittarius’s love of the road and Libra’s taste for the good things can make for a very good holiday.
Beyond the Sun signs
A friendly Sun angle says you’ll probably enjoy each other’s company, and not a lot more. Check for contacts that add emotional weight, like Moon trine Venus, and for ones that could show where the work is, like Saturn square Venus.
