Until it comes out to be true, this could be another person trying to either get money or just her name out there.
As for a wife (will take Bryant for an example), sure they have a lot of money that you can get from them, but what they won't be able to take when they leave is the social gatherings that she is able to attend. She gets to go to a lot of parties and other activities when with him that she won't be able to do if she leaves. Some women need that attention and will give their dignity away for it. Look how much negative reports that she got when he gave her that huge ring and she caved.
