Give you somebody to argue with and the bond holds
Give this placement a person who will disagree well and it settles for years. Mars in Gemini in the 7th house makes the exchange itself the substance of partnership, so what keeps you attached is not agreement or calm but the ongoing possibility of a good argument.
The sign supplies the appetite for verbal contest and the house delivers it into one chair rather than into a crowd. That is why your relationships run on talk to a degree other couples find strange, and why silence between you is a more serious signal than any raised voice.
You fell for how they think
The first thing that held your attention was a mind: somebody who saw the angle, made the connection, refused the obvious answer. Physical attraction arrived afterwards and follows from it. This is a reliable instinct and it comes with one blind spot, which is that intelligence tells you nothing about whether a person is kind under pressure.
Contradiction is how you stay in contact
You take the other side of things your partner says, not to win but to keep the exchange alive, and after enough years it can read as never being on their side. The content is play and the accumulation is not. Say plainly, sometimes, that you agree and have nothing to add. It is a harder sentence for you than any argument.
Two speeds in the same relationship
Where a partner processes more slowly, you have finished the conversation, drawn the conclusion and moved on while they are still forming their first sentence. They then feel steamrolled by somebody who was being perfectly reasonable at speed. Ask and then wait through the whole silence. The gap is not disagreement, it is the sound of somebody thinking.
When it goes quiet, act immediately
Because your relationships are made of talk, the first sign of real trouble is reduced traffic rather than raised volume. Fewer messages, shorter answers, the running conversation losing its thread. You will notice this and explain it away, because nothing is obviously wrong and nobody has complained. Do not wait. Ask directly inside the week, since in your particular arrangement quiet is the alarm and an argument is ordinary weather.
Say the plain thing without the joke attached
You can make anything funny, including the moment where something serious needed saying, and the deflection is fast enough that neither of you notices it happening. A partner ends up guessing at what you actually feel. Once a week, deliver one uncomplicated sentence with no humour in it and no qualifier afterwards. The discomfort passes in about four seconds.
Better as a double act than as a pair
In company you and a partner perform together, finishing each other's stories, running the table between you. It is genuinely entertaining and it is also the version of the relationship most of your friends have ever seen. Let somebody watch the ordinary one occasionally. The double act is a real thing and it is not the whole of what you have.
The half of a partnership who talks to people
Business pairings suit you when the other person does the parts you will not: the accounts, the follow-through, the twelfth month of a long build. You bring negotiation, positioning and every conversation that has to be had. Write down who owns what at the start, because the division that is obvious to both of you now becomes a grievance about the same tasks in year three.
Somebody else has been the mirror all along
You work out what you think by saying it to a person and watching what happens, which means you have rarely reached a conclusion alone. That is efficient and it makes solitude genuinely uncomfortable. Spend a stretch each year deciding something without consulting anybody. Not because the counsel was bad, but because you should know which of your opinions are yours.
Agreements you made verbally and never wrote down
Money arrangements with partners get settled in conversation, adjusted in conversation, and remembered differently by each of you. You are both certain and you are not describing the same agreement. Put the current version on one page this month, with figures. It is not distrust; it is the only way two fluent people ever find out that they disagreed.
