If the choice is only Roxy or Chelsea, then I pick Roxy. I don't like Chelsea, she is self centered, mean and calculating. At least Roxy is a nice person. I think the Doctor needs someone to bring him out of his shell a bit and thant could be Roxy.
I'm with you Spurs, if forced to choose between the two, I'd go for Roxy but I also agree with Pirty. Tanya seems more his speed. And Max and Tanya together still makes me gag.
If he doesn't go for Chelsea then there's something wrong with him. Roxy has a baby that will always be getting in the way of the rumpy-pumpy. You have to take such things into account.
He's got a point there. lol! Booty call is Chelsea, but booty call and probably wanting a commitment is Roxy. Roxy is also capable of doing the booty call thing, but only short term. lol!
edit: Just want to edit to add I also think Chelsea is too young and immature for the doctor. He needs a more mature woman like myself.
