Bingo, brilliant point. He loves her airheadedness. Actually he is an airhead too. She doesn't want to marry him really but she is 32 and frankly the good men get picked off early.So she is "settling" for him,,he is tall, has family money and a good pedigree and is just dumb enough for her to run circles around him, get forgiven and be supported.
They are perfect for each other if not in the eyes of the world. You don't have to be perfect to need a husband and vice versa.
I think there is alot more to this story than the media has spoken of. I am curious about her boyfriend situation from 18 to 25...if she went through ten to fifteen guys in that period...then she is simply unable to stick with one guy. But this will make for a great movie...which I think Drew Barrymore ought to play her. And Adam Sandler as the dimwit groom.
