The bonds that count go all the way down
Scorpio is where your Jupiter learned its manners and the 7th house is where it spends them: the attachments that enlarge you are complete, exclusive and not lightly entered. Pleasant arrangements do nothing for you at all. What this needs is somebody who can stand being that close.
The growth arrives through one bond rather than through a range of them. Your circumstances, your understanding of yourself and most of your genuine changes have come out of a relationship that went further than the people around you would find comfortable.
They have to be able to withstand you
What you bring to a partnership is complete attention, considerable intensity and no interest in a comfortable distance. Some people find it the best thing that has happened to them and others find it too much. Say early what the register is, since the mismatch is not fixable later and both of you will spend years discovering it.
A merely pleasant arrangement will not hold
Relationships that are agreeable and shallow leave you unable to explain why you are unhappy, because nothing has gone wrong. That absence is the difficulty. You have left situations that everybody else considered perfectly good. Ask whether you actually know this person, since your requirement is depth rather than harmony and the two are frequently confused from inside a good-looking arrangement.
Once you decide it is over, it is over
The conclusion arrives internally, sometimes months before anything is said, and after it there is no reopening the matter for you. It is decisive and it is hard on the other person. Say it when you decide rather than when you are ready, because the interval between the two is spent by them in a relationship that has already ended.
What you cannot tolerate is being managed
Being handled, placated or told a softened version registers immediately and finishes your respect faster than any bad news would. You would rather have the difficult truth on the first evening. Say that plainly to somebody diplomatic, since their instinct to protect you reads to you as deception and neither of you will guess why it went wrong.
Your closest friend is probably your partner
The person you are attached to holds the position that other people distribute across a circle: confidant, ally, the one who knows everything. It is a strong arrangement and it puts everything in one place. Keep one friendship that is genuinely independent of the relationship, since the alternative is that an ending removes your entire support at once.
You work best with somebody you actually trust
Professional arrangements only function for you once trust is established, and until then you hold back more than your colleagues realise. That period can take a year. Say what you need in order to trust somebody, since the requirement is reasonable and nobody can meet a condition they have not been told about.
You saw straight through their household
Joining another family, you read the arrangement within a visit: who holds the power, what is not discussed, which relationship is doing the work. You have said none of it. Keep it that way with one exception, since your partner deserves to know what you can see and nobody else in that house is going to tell them.
One person has changed you more than anything else
There is a single relationship in your history that reorganised your understanding of yourself, and nothing since has come close to it in effect. That is how this position works rather than a matter of chance. Say what it actually taught you, out loud, since a formative bond that has never been described stays unfinished business.
Merging money means merging power
You understand better than most that joint finances are an arrangement about control as much as convenience, which makes you cautious and occasionally suspicious. That awareness is an advantage. Write the terms down while everybody is fond of each other, since your instinct is correct and it works far better as a document than as vigilance.
