The first wife thing is a really good point, I hadn't really thought of that before.  I bet that does play a huge role in how she sees things with the houses, she was first and she probably feels a sense of entitlement over that because of having to put up with all of this crap.  I would probably feel that way too.  I don't care what they say, the jealousy has to be crazy between all of them with a lot of things.
