Do you not have an overlapping fundamental agreement with your partner about how the world works and what’s moral values are most important?
Like you’re not gonna agree on everything I know, but “are some people inherently better than others, should a justice system focus on punishment or rehabilitation, is education valuable for society, was the earth created by evolution or God, do you want kids(+ a couple questions if “yes”)” are, in my mind, things you need to agree on with the person you intend to share your life with.
