The 7th house is the house of partnership relations, which includes close friends, marriage partners, business partners and the degree of the person's popularity. For Pluto, this is one of the strongest positions, since the 7th house reflects the sphere of relationships with people, and Pluto is a collective planet.
Such a person possesses a special attractiveness and magnetism, as they are able to attract and influence other people. Pluto gives such features in communication, and therefore such a person can interact with the team as a whole. Imperceptibly to others, he gradually conquers them so that over time they begin to depend on him.
The partners of the owner of Pluto in the seventh house can be very strong-willed, either endowed with a certain power, or these are complex partners who will press on him, demand something, psychologically exhaust and subordinate him. But we immediately stipulate that we also pay attention to other strong-willed planets: if, for example, the Sun is high and in a trine with Pluto, then such a person will be difficult to subjugate, and if the Sun, for example, is in the twelfth house or there are other damaging factors, then he may come under pressure. Therefore, Pluto can play in both directions here, that is, they can put pressure on the person, or he himself can put pressure on others, be demanding. There may be constant psycho-emotional struggle with partners.
Let's also note such a manifestation of Pluto in the seventh house as jealousy. At first, the first signals of jealousy, such a person may perceive as a manifestation of love. It seems like how cute: "He is jealous, so he loves." But the further, the more and imperceptibly to himself he becomes a hostage in such a relationship: "You can't go there, cover this!" - and then only worse. As a result, the partner may turn out to be an offended manipulator and tyrant, from whom it is difficult to divorce.
In his profession, such a person may work as a psychologist, psychotherapist, astrologer, working with the problems of other people. And, as a rule, they are visited by non-trivial, complex clients. The person's partner may be a dangerous profession, as well as businessmen, all law enforcement officers, financiers.
