Venus (love, money, self-esteem) in Cancer squares the Nodes in Aries/Libra today and tomorrow (August 5th). This is a passing influence that could bring a quick spot of tension, but also a push in the right direction.
The transiting South Node (culminating issues) in Aries tells us that selfish action and thoughtless initiation are themes that have exceeded their shelf life. Transiting Mars (ruler of the South Node) in Scorpio adds compulsion to the mix. Even if you or they must have it, it's simply not all about that one, pressing urge. Doesn't matter how life-or-death it feels.
The transiting North Node (path forward) in Libra (relationships) is ruled by Venus, and her square aspect is a skipped step on the path from the South Node to the North Node. From "me first" (South Node) to "us" (North Node). Venus in Cancer nurtures, empathizes and feeds others (literally and metaphorically). This skipped step makes these issues a sticking point. In some way, that energy is being underused, overused or misdirected.
There could be a specific person (not necessarily a romantic attraction) who makes you aware of these issues. The flow of giving/receiving will be out of whack in your relationship with them. You give too much, they give too much, you smother, they're needy...it could work either way. The purpose of the encounter is to turn your attention to Libra (in your chart) and adjust the scales of giving/receiving. Aim for balance and equality.
The trick with Libra is to remember that it's not all about them, either. There's a sweet spot where what you want dovetails with what they want.
This influence is very brief, so you may only feel it if you have natal/progressed planets, angles or Nodes from 19 to 22 degrees of the Cardinal signs.
