Kerry, So sorry you have to go through this. Your family has about the same ages and genders as mine. Looks like you're on the right track by coming here early in the game - much earlier than I did so I'm happy for you. And I'm glad you were the one filing the D, otherwise it could have been messier and you'd have had to wade thru' more insanity.
Canceling the credit cards and asking for primary custody seems like the responsible thing to do - it will make her mad but hang tough and do not yield on the financial and legal front (i.e., stand up for your kids and money as much as legally possible). Do not talk to her about R or the M if you can help it. Do not react to her or plead with her.
And if there's something she wants you to change about yourself that's valid regardless of the D then do it and quietly if it will make you a better person.
