My son has Pluto Scorpio 8th/Moon Aquarius 11th square.
Transit Uranus in Taurus 2nd came along. His wife of 12 yrs came home on a Friday and said "I'm leaving."
He was shocked Moon AQ 11th, didn't see it coming at all.
8th for intimate partner, 11th for breakup, 2nd lost half his income and plunged self esteem into the dirt.
Rulers:
Pluto 8th
Moon 5th (they have 9 yr old child who btw has Jan 12 birthday SA/PL coming)
Uranus 11th
This Moon and Pluto (apex) are part of a kite pattern so the whole thing is set off.
