Venus in Scorpio loves intensely. In this system it is an afflicted position: its reading looks at the difficulties that can arise when insecurity mixes with conquest.
Difficulty can increase their interest: they work hard to win someone over, lose enthusiasm when they feel the relationship is completely secure, and come back closer if they sense distance. That swing can be painful both for the person living it and for their partner.
Jealousy and a sense of being at a disadvantage may be present even if they try to hide them. They want security and, at the same time, may feel less attracted when they believe there is nothing left to win. Hence the ambivalence: they pull away at an expression of affection and protest when the affection is withdrawn. The great love always seems to lie in what they don’t yet have.
This doesn’t mean their declarations are necessarily false. They may sincerely feel the intensity they express in that moment and still find it hard to sustain when the dynamics of the relationship change.
Keeping interests and a life of one’s own can keep alive the desire to get to know each other. That autonomy belongs to both; it isn’t about provoking insecurity or deliberately withdrawing affection to hold on to someone. Stability asks for recognizing that back-and-forth between closeness and distance, and being able to talk about it.
