I'm sorry your wife is still acting like this. I bet she doesn't seem like she's even the same person. My wife acted like this, too, like I was a terrible human being, the lowest of lowest, like I was doing to her what she was doing to me.
I would want to look her in the eye, too. My wife seemed to really hide from me at times, like she was hiding from her guilt and feelings. I'm so sorry you are dealing with this, but I believe you are and will continue to be a much better man because of this hell you've been through, no matter what your wife decides to do.
What are these papers for, exactly? If signed, will they set a final date for a divorce? Will they just declare whose property is whose, and declare the two of you as living separate lives?
I have believed all along, as have others that have visited your threads, that she is in a relationship. My wife was, and she didn't start to come around until the relationship with POS had ended. She acted exactly the same as your wife, from what you have told me. I would not trust your wife's word that she is not seeing anyone, even if you have never caught her in any other lies before. I never knew my wife to lie to my face until she was pulling out of our relationship. She was not herself for several months there. I suspect your wife is very much not herself, either.
I was reading a forwarded email from my mom, several weeks ago, about things the author of the email had learned throughout their life, and one line struck me: "I've learned that the greater a person's sense of guilt, the greater his or her need to cast blame onto others."
