The deep end is not a polite place
Your Venus wears Libra and works out of the 8th house, so your considerable social skill is being applied to the one area where it does not entirely work. Real closeness involves jealousy, need and things said clumsily, and none of that can be arranged into something graceful.
You will try anyway. The instinct is to manage the intensity, to phrase it well, to keep it civilised, and what that produces is a relationship that looks admirable and never quite arrives. The unmanaged version is the one that gets you what you actually want.
Fairness applied where it does not quite fit
You want intimacy to be even: equal disclosure, equal need, equal investment. Depth does not distribute itself that neatly, and somebody is always further in than the other at any given moment. Let the imbalance stand for a while. Insisting on symmetry here tends to stop the whole thing at the point where it was about to become real.
Shared money, negotiated properly
Joint finances are territory you handle well: the terms discussed, both positions heard, an arrangement that neither party resents. That is a genuine skill and it prevents most of what goes wrong in this area. Just be sure the arrangement reflects what you actually want rather than what avoided a disagreement on the day it was made.
An aversion to the ugly scene
Raised voices, tears, an accusation made badly: these are worse for you than the underlying problem, and you will concede almost anything to prevent one. People learn this quickly and some of them use it. Sit through one. The scene ends, the relationship survives, and you discover that your terror of it was doing more damage than the thing itself.
Endings handled with more grace than honesty
You conclude relationships considerately: nothing said that cannot be taken back, the other person's dignity preserved, everybody behaving well. What frequently goes unsaid is the actual reason. Say it, kindly and plainly, since the person you spared is left constructing an explanation from nothing and will usually construct a worse one.
Say the ungraceful thing once
There is something you want, or resent, or are frightened of, that has never been said because there is no elegant way to put it. It does not need to be elegant. Say the clumsy version to one person who has earned it, and notice that the closeness you have been trying to arrange arrives by itself immediately afterwards.
Suppressed conflict has a physical price
What you decline to say does not disperse; it settles, usually in your sleep and your digestion, and it stays for as long as the situation is open. You will attribute it to almost anything else. Notice the pattern once and act on the situation rather than on the body, since the body has only ever been reporting.
Kept out of other people's quarrels, at a cost
When two people you know fall out you can see both cases and refuse to take a side, and both of them experience that as abandonment. Neutrality is not the neutral option. Choose, when somebody has genuinely been wronged, since your unwillingness to judge leaves the person who was hurt entirely alone with it.
You are trusted with the delicate negotiation
Difficult money conversations, contested settlements, situations where two parties need an outcome nobody has to be ashamed of: this is where your talent becomes commercially valuable. Take work of this kind deliberately and price it as a specialism, since being pleasant in a hard room is a scarce and consistently underpaid capability.
Nobody should be worse off than the other
Your instinct with joint assets is to make sure neither party is disadvantaged, and you will accept less yourself to achieve that. It is honourable and it has cost you real money at least once. Aim for terms that are genuinely fair rather than terms that feel comfortable, since those are not the same and only one of them survives inspection later.
