I am of the opinion that everybody has to mantain their routine in the relationship... at this point she hibernates at least with her public appearances...
She should do promotion like nothing happens... Harry so his public appearances and she sits at home waiting him... that is not modern....
There is a number of good reasons why she's not out there doing interviews right now other than she's staying at home waiting for Harry. One being that anywhere she goes, the attention would shift away from the show or her clothing line. Contrary to popular belief, not all press are good press. Especially if you actually have something of value to promote. If you are a reality star, sure all publicity are good. But that's not the case here.
