This is exactly right. In spite of all his money, Bezos is just a goofy looking nerd who was probably constantly rejected in high school. Therefore he has absolutely zero taste in women.
In addition to being half plastic and old she has an illegitimate kid by a ex-football player. That would rule her out as wife material for most self respecting men immediately. Bezos is one of the world's richest men yet he's marrying a trailer park chic, that shows massive insecurity. Sanchez is used up mistress material, there's no way a guy with his status should be anywhere around her.
