UPDATE: I haven't posted here for several days. I guess I felt like giving up. She went to get the divorce papers but hasn't filled them out yet. Then yesterday and today, she has been fighting with the OM. She is very angry with him because she doesn't want to do things the way he is suggesting and she has asked him not to contact her more or come to her work. She is even interested in getting a stalking injunction against him if he can't stay away this time. But she wants to wait and see if he tries to come to her work again. And he says that he doesn't want to contact her anymore after seeing another side of her (yelling). Nevertheless, she tells me that our problem is not about him and she is still not interested in reconciliation and she still plans on filing for divorce.
Ken, all cheaters say that! It would ruin their rationalization process for doing what they've done if they actually admitted the problem was the OP. You can't argue that with them though.
