From looking back at the books earlier today, more of what works seems to involve things that make interactions with your S more positive/effective. So, if talking about serious issues before bedtime tends to yield anxiety, frustration, etc. then try talking at another time. I'm using an overly simple example because even I am struggling with what works in my situation. What works might be Rock thinking about his values and preferences related to communication. Where does that align with hers? Where doesn't it? Where might they have to compromise? Looking back at examples where they've successfully communicated (the "exceptions" as MWD says) might help define what worked then and might work now. Ideally, it is a "win-win" that yields a productive discussion between the two of them while preserving Rock's integrity, boundaries, and overall well-being.
