My wife was similar. Complained about the organization, lack of information, etc too. When when called to confirm the registration and needed to talk to her, she at first refused to get on the phone, then got on and told the woman that she didn't think we were good candidates for the program, and handed the phone back before she was done. She told me she during the week that we should cancel, that she didn't want to go. Had this conversation a few times.

It was touch and go, but she went.

Play it cool. Good luck -
