If anyone leaves it should be the cheater. I can't believe you're still keeping her secret especially if you've decided its over. With that said, if she wants to start a new life with OM quickly then you can use that as leverage to get everything you want in a D. Of she agrees to your terms then you'll let her out,of the M quickly and won't expose her as a whore. If she wants to fight you then her whorish affair gets added to the D filing so it's official public record for the world to know. Also, you should already have lawyered up and be the one filing. Never wait for it.
