According to The Plain Vanilla Astrologer

People with Mercury in the 7th house usually seek mentally stimulating relationships. Sometimes the partner is a Mercurial type, having this planet (or Gemini and Virgo emphasized) in the chart. Occasionally the partner may be highly strung or even mentally unstable (particularly with afflictions from Uranus or Neptune or Pluto). Initially the attraction is likely to be towards the partner’s mental creativity, the stimulating companionship he or she provides, and the combined exchange of ideas. The individual may be seeking an intellectual as a partner in order to fulfill his or her neglected abilities in this direction. A 7th house Mercury also indicates that the individual may require constant change and variety in his (or her) relationship. So Mercury in this position is not always the best indicator for long-term partnerships. Perhaps because of the eternal-child quality of this planet, the individual with a 7th house Mercury sometimes has a much younger partner. However, the usual qualities of the partner, and sometimes to the fact that he or she is involved in journalism or education, for instance, two professions typical of Mercury. 

If you have Mercury in the 7th house and lack sufficient mental self-assurance in your own thoughts and opinions, you may face a tendency to rely on others for your thinking process. You might doubt your own intellectual abilities and believe that other people are smarter and better at expressing themselves. This lack of confidence in your own mental prowess could lead you to delegate decision-making and seek external sources for guidance and validation. The 7th house, which is associated with partnerships and relationships, can influence how you interact with others on an intellectual level. With Mercury in this house, there is a risk of giving away your mental power to others, either knowingly or unknowingly. This could manifest as adopting someone else’s ideas and opinions as your own, feeling influenced by the thoughts and beliefs of those around you, or feeling swayed by persuasive arguments from others.

You may constantly seek validation and approval from others in your intellectual pursuits, looking for reassurance that your thoughts and ideas are valid. This desire for mental companionship and approval could potentially affect your decision-making process, as you may prioritize maintaining harmony in relationships over expressing your authentic thoughts and opinions. To overcome these challenges, you can focus on building your self-confidence and cultivating a strong sense of your own intellectual abilities. Work on being more assertive in expressing your thoughts and opinions, even if they differ from others’. Seek out diverse perspectives and engage in healthy intellectual debates to expand your understanding and gain more confidence in your ideas.

Learning to value your own mental contributions and trusting in your ability to think critically and independently will empower you to have more balanced and authentic interactions with others. By embracing your unique intellectual perspective and not shying away from expressing your ideas, you can foster more genuine and meaningful connections with those around you, leading to more fulfilling and constructive relationships.

Howards Sasportas says,

With Mercury in the 7th, many problems can be ‘worked through’ if they are discussed and analyzed. Some people with this placement may be fairly (or should I say ‘unfairly’?) critical and judgmental about ‘those little things’ which their partner’s do which annoy them. Fortunately, the antics of the god of Mercury remind us that a sense of humor about such things is the great balancer.

However, while you naturally possess some communicative gifts, there is still a need to develop and refine your communication skills continuously.
