Don't forget that these things take a CRAZY amount of time. She's still totally infatuated with OM and has the infatuation drugs in her brain that go along with it. You can't do anything about it...It's like dealing with an addict.
So - let her go to the addiction.
The drugs wear off, they will have to face the reality of what they've done and how it impacts their families.
You have a big decision at this point, too. She goes - you can decide you're not going to stand anymore. She goes - you can decide you're going to stand for your marriage. She goes - you can decide that you need some time to decide. All work.
But let her go. Don't fight her. THAT ALONE will come as a shock to her. That will be a big 180. "I'm leaving." "Okay. I'm very sad. Our kids will be very sad. This is not what I wanted. But go."
That very act alone might start to put some doubt in her head.
