If she asks how the C is going say it is going well. No details. None. Then do like dburt advised with looking good, asking to drop the kids off early, etc. Except, I wouldn't say anything about dealing with issues and not letting life pass me by. If she wanted to know what was up then just say that you are just living your life. Again, no details.
You WANT to be a mystery.
