In astrology, when analyzing relations, particular attention deserves two planets: Jupiter and Saturn.

Jupiter – Venus aspects

Jupiter is a planet of luck, expansion, and fortune, and any good aspects of his Jupiter to your Mercury, Venus or Mars, are called “Seal of Happiness”. The same goes with your partner “seal of happiness” is any positive aspect to his Jupiter. For example, Jupiter of your partner is in connection with your Venus. This is perfect. The other very good aspect if your Venus is in opposition to Jupiter of your partner. – To my mind, this is one of the best aspect of marriage. Good aspects of your Venus and his Jupiter give ease of understanding, smoothing rough edges. Even a square between Jupiter and Venus in synastry does not bring anything terrible because Jupiter is a planet-benefactor.

Such positioning enhances the likelihood of having high sexual pleasure with your partner. Another indication is that your partner will help you in all your creative endeavors. He will continuously inspire you and provide authoritative advice.

Jupiter – Neptune Aspects

What does it mean to your relationship when your natal Neptune is in conjunction with your partner’s Jupiter?

This is a positive aspect: partners positively stimulate each other regarding self-education and improvement of personal intellectual potential. They like joint travel and sightseeing tours.

Both partners are actively engaged in spiritual self-perfection and charity. They are socially active and are always on the side of justice. Their house becomes a central place for practicing and other spiritual activities.

“Jupiter” personality considers “Neptunian” personality to be intuitively enigmatic, even in matters relating religion and philosophy, whereas Neptunian personality, for her part, considers “Jupiter” personality in this respect to be purely traditional kind. In general, they both are very sympathetic to each other; they understand and respect feelings and emotions of one another.

Personal and mutual expansion and growth are very much a part of your romantic relationship. You are more likely to take risks based more upon an abundance of confidence in your beliefs than upon practical considerations. If your romantic partner’s Neptune is in conjunction with your Jupiter, your presence seems to brighten his/her spirit, expanding your partner’s awareness of infinite potentials and possibilities. Your partner is looking at the world as it could be and as he/she would like it to be. Your partner’s sense of idealism can blow his/her compassion out of all proportion to your present financial means. You will both have to accept the world as it is to explore creative ways to manifest abundance.

Jupiter’s personality has a positive effect on a person’s first house, adding value to the self-expression as well as spiritual self by helping to develop a positive outlook. Jupiter personality encourages forces of the First House person concerning personal spiritual self-improvement and helps a person in a positive and constructive social self-expression. The character of the First House, in turn, helps to increase Jupiter personality to realize ideas and projects in practice. The nature of the first house charges Jupiter personality with energy and strongly supports Jupiter personality to achieve greater appreciation. With active cooperation, between partners are generated positive constructive and creative mutual relations in cultural, educational, spiritual, philosophical, and social spheres of life. Partners charge one another with energy and vital activity; they love to travel and always raise their intellectual level. At the same time, partners are quite actively engaged in building relations considering family highly important part of their life together. Partners are good friends and spend a lot of time together, feeling very happy with each other.

I happen to believe that poorly aspected Saturn can give complications in relations even you seem entirely happy. You may find out that a partner deliberately destroys your reputation and lies about your relationships with others. You need to check of course of other indications in the horoscope. Saturn hits when you least expect it.
