I have to tell you that I laughed when you said that from time to time you forget about the p/a dance. I still do that so don't feel bad!
Funny that you should mention your previous experience with C. My story was much the same and my reasons for not going were that I already felt like my marriage was a sinking ship. Turns out my gut was right and that session sealed the deal. He wanted permission to do what he did. See people go to C but if they're not honest about themselves or their feelings they take what they want to make their case. I'm sure his reasons for going were not to save the marriage as much as to be able to say he tried.
Fast forward a year. Now it's your turn to ask for what you want. If he's sincere and is on the same page he'll do whatever it takes, bottom line! If he's hesitant or posturing you pretty much have your answer. Of course it can only help you to have a professional to bounce any confusion you may have off of.
