I think you did a great job with H!! Interesting about the emotion at the end of the conversation! Sounds like your C gave you some good advice!
I know it is frustrating and we want to "shake" them so they wake up and realize what they are missing by leaving us!!! It is about HIM, though and you can only control yourself ~ That has become my mantra!
Happiness is like a butterfly: the more you chase it, the more it will elude you, but if you turn your attention to other things, it will come and sit softly on your shoulder.... (thoreau)
