I’m Blue,,,, He’s Red. Someone told me My Saturn squares His Mars ruins the whole thing but idk how true that it is, this is the first time a man has been so persistent can anyone tell me how this would play out?
For one thing, there are so many aspects that take place between two charts, no one of these is a make-or-break aspect. It's a sum of things, a balance between the positive and negative.
Your descendent is ruled by Saturn, and your Saturn is conjunct his descendent. His mars, co-ruler of his descendent, is conjunct your descendent.
In addition, mars in Capricorn and Saturn in aires are in mutual reception.
Yes, mars square Saturn is not an easy aspect to handle, but in your case they are so closely tied to both of your descendents that this aspect acts as a glue to bind you together. There is an inter-changing of energy between your marriage houses and the planets there that is very strong and compelling.
