The partner as a window
The 7th house is one-to-one partnership of every kind, and Jupiter here says much of your growth happens next to someone. You’re drawn to people who know things you don’t, believe in something, or have seen more of the world. A partner might sharpen your sense of right and wrong or get you thinking about faith in a new way.
You also bring out the best in others, often without trying. Business partners, friends and dates tend to become more generous and good-humored around you, which makes you easy to team up with.
Big personalities and big expectations
Picture saying yes to a partner’s idea of a month abroad, then realizing on the plane that it was always their plan, not yours. Jupiter here can hand a partner the job of supplying meaning and optimism for both of you. You may also be drawn to large characters who promise a great deal: some deliver, and some mostly talk. Look at what someone does in the second year, not only the first month.
Keeping the scales level
Strain usually shows as pride or excess: overspending to keep a good time going, refusing to admit the relationship needs work because you were sure it was the right one. Keep growing on your own as well, through a class or a trip that’s yours alone. A partner can widen your life without being the only door out of it.
It also helps to say plainly what you’re hoping a relationship will give you. If you want someone to grow with, tell them, and listen for whether they want that too. Some people are looking for a calm harbor rather than a bigger world, and that’s a fine thing to want, but it’s a different relationship from the one you’re after.
