I think she doesn't show Hairy Watchman's face because she is not proud of him. As someone already said, she shows us intimate details of their relationship, at this point his face is nothing. I think the fact that Jim moved on with a model (who also happens to be more educated than Tanya) has something to do with it as well. I don't find Jim attractive at all and never have, but today's Tanya isn't attractive either IMO, and being as vapid as she is I don't think she can pull anyone "better" than Jim (at least on paper). She wants to show that she moved on so people don't feel sorry for her, but at the same time worries that people will say she "downgraded" if she introduces him. Sorry if I'm being mean...
