Not only is it bad DB'ing - it is a bad idea all around. Whether or not your W talks to OM, or whether or not she chooses to work on the M needs to be HER choice. You telling her what she should do or what you want her to do will only push you further from your goal. She needs to see you as a confident person in order for you to attract her back to you. Showing insecurity about OM (at the point your R is at) is showing the complete opposite.
w.r.t to the dusty bedroom - if she says something like that - make it an opportunity to show her an action. Just take the canopy down for her and dust the room for her. Don't ask her if you can do it. And then don't ask for praise from her for doing it either - she will notice and it will mean more if she comments on it on her own w/out being prodded.
