She may know already but hasn't said anything. Women are smart. Maybe this is bad advice but I wouldn't tell her, she could take it the wrong way. Keep working on your PM recovery. If you get into the upper echelons with 100+ days, for example, and feel confident that you are done with PM, maybe then you could tell her with confidence that you won't do that any more. Then again, I haven't been married in over 20 years so what the heck do I know?
