I only see two that could be a bit (or more than a bit) ambiguous...
- Balance time, attention, expenses
- Give information as needed or solicited
What one person's opinion of balanced is and what another (even a spouse) feels may often be two different things.
On the second, is information only to be given when solicited/asked for? Or is the partner with the information supposed to know when the other partner needs said information? Would it not be better to just always give information?
