A companion, not a keeper
The 7th house is where your Sagittarius Venus goes looking, and what it wants is somebody to go along with rather than somebody to settle down with. The distinction matters enormously to you and is invisible to most of the people you have tried to explain it to.
What you are offering is genuine and it comes with a condition. You will be loyal, honest and entirely present, and you will not be contained, and a partner who tries to narrow the arrangement will find the whole thing loosening in their hands.
Honesty as the working standard
You say what is true in a relationship, including the parts that are inconvenient, and you expect the same back. Diplomatic silence feels to you like a kind of contempt. That standard produces unusually straight relationships and it also delivers some sentences the other person was not ready for, so pick the hour rather than the sentence.
Drawn to somebody from elsewhere
A partner from another country, another background or an entirely different world holds you far better than somebody from the next street. The gap is part of the appeal rather than an obstacle. Name the work that comes with it, though: two sets of assumptions have to be translated deliberately, and calling that a project rather than a problem is most of the solution.
Restless the moment it feels final
The point at which a relationship is declared settled is the point at which something in you begins looking around, and it has very little to do with the person. Notice the trigger rather than acting on it. Build something new into the partnership at exactly those moments, since the wanting is for movement rather than for somebody else.
You leave rather than repair
When something goes wrong your instinct is to conclude that the arrangement was mistaken and to go, rather than to sit through the difficult stretch and find out what it was. Some of those endings were right. Stay through one you would normally have left, since you have no data at all about what happens on the other side.
Commitment with the door visibly unlocked
You can be entirely faithful and you cannot be enclosed, and those are different things that partners regularly confuse. Say which one you are offering, in plain terms, early. Most people can live with a great deal of freedom in a relationship provided they have been told it is the arrangement rather than discovering it.
A relationship that confines you shows up physically
When a partnership starts to feel narrow you get restless before you get unhappy, and the restlessness reaches your sleep and your appetite first. Treat that as information about the arrangement rather than about yourself. Something needs to open up, and it is usually smaller and more practical than the drastic version you have been contemplating.
Your partner has to like the travelling
A great deal of your shared life happens away from home, and a partner who dislikes leaving will gradually turn your relationship into a negotiation about departures. Establish that early. It is not a small compatibility question here; it is the one that determines whether the next twenty years are enjoyable.
You work well with somebody who argues back
Professionally you are best paired with a counterpart who will contradict you properly, since your enthusiasm needs something to push against and agreement makes you careless. Choose the collaborator who disagrees rather than the one who is easy, and say at the outset that this is what you want from them.
One of you is going to be the cautious one
In most of your partnerships somebody ends up holding the sensible end of the finances, and it has rarely been you. That division works perfectly well provided both parties agreed to it out loud rather than arriving at it by attrition. Say who is doing what and why, since an arrangement nobody discussed turns into a grievance about character rather than about money.
