B,
I agree w/the other posters...any time that he brings up the situation about the divorce and/or paperwork, advise him to speak to his lawyer.

Please don't send the email to him...he already knows how you feel about things and you do not need to repeat yourself about the divorce.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
