Once again I completely agree with you on this. I believe he needs to point out to her that she cannot expect him to read her mind, I mean...she can't read his.
I said pretty much verbatim the same thing you suggested...to my H at one time. But I think I said something like..."you won't tell me what's going on in your head, you won't tell me how you feel....you expect me to guess. You are willing to let me flounder away, THAT is not a very loving thing to do!"
This of course was in my very fledgling days on this BB. But it did make him stop and think, if even for a moment.
