For me, sag is my 8th house. As I wrote in another thread during the pluto transit, I did a lot of deep psychological work finding out who I was and also how others think. I went from a co-dependent mentality to being highly and too independent.
Most of my relationships during that period ended quickly whenever things start to get close and intimate. I have jupiter-neptune at the end of the 7th, looking into the 8th and sacrificing my values to other people's to get along with them was something I did because I thought that was compromise. Every magazine article or book talks about how relationships need compromise. Except whenever I did, people still walked away. I was always too much of a giver (nep) in relationships, because it keeps you free (sag) of debt (8th)
Now that transitting saturn has come into sag and my 8th, I'm getting a very clear message that I'm not willing to play to other people's values. Or more precisely that I'm only going to spend my time and effort on people who have similar values and levels of psychological health to begin with.
I'm testing people early on to see whether they're capable of intimacy, whether they're capable of being a giver (not just a taker), I'm finding out what their values are.
