why do you feel the need to write the letter? You've told her this already haven't you?
I would wait on it...I've only skimmed your sitch so forgive me if I missed why the letter is important.
I agree w/ Rob, the financial stuff will need to wait. If she has questions she can e-mail you...good job on the NC...it's a better place to be...i'm right there w/ you.
W moves out today, I slept like 2 hours and not feeling very PMA...
