Even your best friend could sue you for alimony. What happened to Christine's almost doctor boyfriend? Did she dump him for the lawyer.
So Barb and Richard actually went for nuptials, maybe they omitted new Christine specifically for that, because I'm sure she wouldn't be happy to find out that Richard could marry someone that wasn't her. He didn't even tell her that he was engaged. That was probably what came with we are living together for only platonic means.
Barb is also very adamant about remaining in the country, what does she really have to stay for; her job, Christine or even a wacky...
It only takes someone like Christine to turn a life threatening condition and turn it into a way to pick up a doctor for sport.
So 'The Mole' turned into the chocolate speck, that one was odd, couldn't she have spotted that flaw herself.
I found it mildly disturbing when Richard only got turned on when poor old Christine was suffering. As the seasons progress and we understand the type of person Richard is, we also imagine the type of husband he was and the divorce becomes more apparent. Of course Christine had a part to play in the craziness, but Richard's crazy is just bizarre.
