Composite Pluto in 12th house:
"Pluto is the planet of death and rebirth, regeneration, obsession, fanatical behavior, power and the abuses of power. This position of Pluto will tend to make you dig down to the roots of any problems you are having so that you can work through them. Your relationship will result in an inner transformation in both of you and these changes will be for the better. Whatever problems you encounter must be dealt with immediately because when Pluto's energy festers for too long, it comes out in explosive ways, thus bringing great difficulty in your relationship. There will be a high intensity of energy around you, especially when you are together. This can frighten the people who come into your presence because the power is so intense that they don't know what to make of it. People can often turn against you and do things behind your back without any provocation. The 12th house is the house of secret enemies and your actions will trigger people to work against you. Therefore, it will be necessary to be honest and upright in your approach to people and make it very clear what your intentions are in any situation..."

Do you and your partner have composite Pluto in the 12th house? What's it like?
I have this with the ex. This explains a lot...the obsession and intensity and transformation.
I have this with my husband. Jupiter is conjunct Pluto in the 12th in and conjunct the AC so it feels even more intense. It trines the Moon and sextiles Venus as well.
I do feel as though, at least in private, we are the epitome of a Plutonian couple. All explosions and chaos...how do people say it? Like throwing gasoline on a fire.
...and it is like regeneration sometimes, but like an exhausting and bloody birth, over and over and over and over...
I have this with my SO. Our ASC is 27 degrees in Libra and our composite Pluto is 26 degrees Libra. We aren't explosive or chaotic, we are actually quite calm.
