I am pretty new to this board and to your sitch. I wanted to offer you a couple of pieces of input. These are from my perspective only, and you and anyone else on here are free to disagree.
It is fine for you to feel anger at times, that is perfectly normal. However, I would not recommend you show any anger or frustration toward your wife. If you feel angry...log onto this board and let it rip.
I believe your wife is having doubts. I think there may be more that you can do, but cautiously. For instance, if your wife asks you about your C sessions, tell her about them. You don't have to go into great detail, but if she asks about them...she may care. If she doesn't ask about them, that's called indifference, and you don't want to be there!
Part of loving her is trusting her. It doesn't appear in your posts that she has done anything to violate your trust. So trust her until proven otherwise.
I maybe should have included this up where I talked about anger, but do not be adversarial or confrontational with your wife. If she is the WAW, her emotions are right on edge anyway. You need her to have time to REDUCE her anger and frustration toward you, so I would not be confrontational or demanding with her.
Do not demand answers because you think you need an answer on something now. The truth is....you don't. You need to make time your friend when dealing with your wife's emotions.
Here's the final thing I've got for you right now. Think of every decision you make through the eyes of your wife. Think about how she would FEEL about it. You can LOVE your wife back into your relationship.
She FEELS like SHE is the one who has been hurt (thus the term WAW). So around her, you've got to let your feelings of hurt go for now.
In regard to how she feels, be compassionate TOWARD her. Love her. Protect her.
Just my 2 cents as I continue to learn things to save my own M.
