I really hate dignifying some of the crap posted on this thread, but its time to put it rest.
First, Charles is a good friend of mine - I've known him for a few years. We are not now, nor have we ever been a couple.
Second, Charles takes care of Abby when I'm traveling - and he also lived here at the house for about 8 months. He's become very attached to her, and she's very attached to him.
Beyond that, the details of his life, mine or anyone else on the show are absolutely none of your business. You have a problem with that, watch another show.
