Thanks for the clarification...but you qualifying her demands as "ideals" clearly shows you're taking one of them as being perfect and always-right and the other as needing to be re-educated. This is not a solid foundation for a relationship, to take your house metaphor.
A towel should not be left on the floor, anyone can agree, but on less obvious topics none of them can be credited as the unique source of Truth.
-always hang up towel after use
A relationship is like building a house, you can build one with out a ruler, but it will probably be more stable if you use a rule®.
These ideas/rules aren’t all equally important, but they provide a rule for straightening out or constructing a more stable house.
Note: this is related to a whole topic of life satisfaction and rules :)
