Why would she say it had to do with your behavior if she was thinking about D or OM? Doesn't fit.
I know, it drives me nuts for someone to hint at something they want to discuss later! Why would she even bring it up? Is it her way of preparing? For what? Who knows! May be another one of those issues in the past she still holds against you. That would be my first guess.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
