Mars in Libra men chase by orbiting and leave by attrition. They mirror you, keep a silent ledger, wait for you to declare first, then go polite, disappear, and call it incompatibility.
Venus in Taurus women don't stay because they're in love. They stay because leaving feels like setting money on fire, and that is the one thing their body refuses to do.
A Moon in Gemini does not fall in love - it gets interested, then mistakes interest for love and talking for being known. The four stages: interview, translation, drift, exit interview.
