Does Venus opposition Pluto mean jealousy?

It describes a contest over what is held, and jealousy is one form that takes. Possessiveness, secrecy and an unusual reluctance to be casual are others, and they do not all come from the same place or respond to the same thing.

Is it always about somebody else?

No, though it is almost always described that way first. An axis has two ends and both belong to the same chart. The end that appears to be arriving from outside is generally the one that has not yet been claimed.

Is this harder to carry than Venus square Pluto?

Neither is harder. The square keeps the pressure inside one person, where it reads as compulsion. The opposition puts it between two, where it reads as a relationship that cannot be conducted lightly.

Aspect

Venus opposition Pluto

Venus opposition Pluto is depth arriving from the far side of the room. Venus is attraction and what is judged worth having. Pluto is an outer body, read for the transformation of resource patterns — what is held, what is spent, what will not be given up. Set across an axis from Venus, that stops being a private matter and becomes a negotiation.

Which is why this contact gets described as being about power. It is more exactly about who is holding what, and whether either party has said so out loud.

What gets held, and by whom

The transformation Pluto is given is not adjustment. It is replacement: a pattern of holding does not get modified, it goes, and a different one arrives. Placed opposite Venus, the pattern under replacement is the one governing what a person will and will not surrender to somebody else.

An opposition is lived from one end and met at the other, so the intensity in this configuration is usually experienced as belonging to the other person — their jealousy, their seriousness, their refusal to let a thing stay casual. That reading is rarely a fabrication and rarely the whole account, because the far end of an axis is not often occupied by accident.

The characteristic movement is exposure. Something held privately — a preference, a dependency, an amount of need — becomes visible to another person, and once it has been seen it cannot be un-shown. Attachments formed on this axis are hard to leave for that reason more than for any romantic one.

How it tends to show up

Attractions to people who are noticeably more serious about it than the situation warrants.

Discovering the size of a need only when somebody else names it aloud.

Negotiations about closeness conducted almost entirely in what is not said.

Endings that require a clean break, because a partial one does not hold.

What changes the reading

An opposition is granted the widest margin in the scheme, alongside the conjunction, so it is claimed frequently. Only the near-exact ones read with the force described here.

Pluto moves slowly enough that its sign describes an age group rather than a person. The two houses the axis runs between are where this becomes specific: one names what is held, the other where it gets exposed.

Whether this is lived or met depends heavily on the rest of the chart. Charts with an appetite for intensity of their own occupy the far end themselves, and the pattern turns inward instead of arriving through somebody.
