Jupiter in Sagittarius brings optimism and joy to a couple, even in the midst of difficulties. They may see a problem as something passing and trust that they will find a way out.
That optimism sometimes makes it hard for them to understand why a situation causes so much sadness in another person. Their way of putting the problem in perspective can be encouraging; they also need to listen to how their partner is experiencing it.
They value the rules they consider fair for the community and are bothered when they are broken. People can trust their word, make agreements with them and delegate responsibilities to them.
They don’t always seek power, but they usually take it on naturally when it falls to them. Authority appears linked to the trust they inspire and to their respect for shared commitments.
