Btw, this is really helping to reduce my PTSD symptoms. 
For example I'm seeing rules abusive people in my past have tried to set for me to follow. (Never confront them or theyll victimize you far worse, never resist their orders, always stay quiet about what theyre doing to you, etc...) Instead of getting hung up on those rules and my opinions on them, just see the the purpose of the rules. (The purpose of the rules in this case is for them to tightly control and victimize someone that will never leave or expose them. That is the whole story and you don't need to storytell any further if you catch yourself flashing back.) If the purpose of their rules and your values don't line up, drop them immediately.

It describes the relation between the two as generally reciprocal, but the material base is the dominant in that it more often shapes the superstructure than vice versa.
The rules and values are just a result of material conditions and class relations. Morality is a product of material forces and is not static.
