Keep being Mr. Perfect if it is what you want. If she can't deal with you being who you want to be, how is that your problem? Why do you have to DO anything about it?

If someone called me "Mr. Perfect" I'd probably respond something like "Thanks. I'm not there yet, I've got 2 more lbs to lose and I'm not quite done with my novel yet, but I should have the draft to the editor by Thanksgiveing".
