I'm not liking this, to be honest. It's rife with conflict.PLUTO, SATURN, and MARS are not easily energies to integrate, and most of these are in conjunction. MARS conjunct PLUTO can be a powerful tie if both individuals are emotionally mature and honest with each other. Otherwise, it's a battleground: issues of jealousy, possessiveness, the battle for control and dominance, power struggles; bad things.
Namely, that MARS-PLUTO is conjunct SATURN-PLUTO in a 12H synastric overlay. This is the classic incidence where deep-seated resentments build way beneath the surface, until they explode, and very often in incidents of violence.
SATURN-PLUTO is the bomb, and MARS lights the fuse. You have to be EXTREMELY careful with a configuration like this; the potential for it to go very, very badly is high.
Here, the VENUS square to the other person's MARS is yet another conflict. As the natal MARS is 2H, this involves, again, issues of possessiveness and ownership.
This is repeated on the other side; with MARS square VENUS.
In either case, issues involving romance and relating are going to set off this dangerous configuration.
To top things off, MOON conjunct URANUS brings emotional volatility, fits and starts, and lacks stability.
SUN square URANUS furthers this sense of unpredictability and conflicts regarding independence, freedom, and what constitutes a framework.
And, I can't tell without degrees, but it appears that the other's MOON is either opposite, or quindecile, the PLUTO-MARS conjunction, and their natal SATURN-PLUTO-MARS.
Again, it returns to that configuration. It's prominently aspected throughout the synastry.
Of course, all things can be handled with enough love and maturity, but this is a VERY rough one. Clearly, the two of you have some very difficult karma to balance.
