I second a no vote on the letter. Think of the seesaw analogy in DB--if you are the one that keeps putting so many heartfelt things out there, he doesn't have to do anything, he can continue to do his best impersonation of a wall.
I wrote a quote down from either the DR or DB book (I get them mixed up now that I've read both!) that I think applies:
"Without me pointing fingers, he only had himself to look at in the mirror that night."
It is in the shelter of each other that people live.--Irish proverb
