I also think it will be hard for you to get somewhere w/ your W unless you are in front of a disinterested party where your W may feel safe. I talk from experience here. It was amazing how I could say something to my W and 1 hr later the C is saying the same thing and she is over there nodding and agreeing whatever. This I say from the last time I went through this. SOunds like your W is still to angry with you to have any productive ocnvo.
You know CVA, I think the same thing, that is why I keep on inviting her to see my C, it is Christian based C, as you know she only see a C, when she takes my DD11, but they only talk about the issues that my DD11, has and not my W's. She doesn't think that she needs C, but as you and pretty much everyone who knows anything about my sitch, knows she does. I just keep the door open, you know. Praying that she will one day open her eyes, and see what she has done to herself, the kids, and me. I am going to be fine, I have God, my family, friends, this BB, and my C, so I will make it with or without her. It's her (she has no one, other than the using and worthless OM, her unsupportive family, they think she is nothing more than a screw up and really no friends) that I worry about. Take care.
