She would leave him if he didn’t marry her and give her long term commitment. Bezos probably figures 7 year prenup covers the window wherein she’s likely to divorce.

There is a good series called “Who wants to be a Billionaire”.
Talks about the reality of being super wealthy and the problems they have. There is an episode on finding a wife. They talked about matching services and said for a female it’s basically give the the Billionaire constant sex and then don’t talk about their work or give opinions.
Many prenups apparently have year targets. So there is 5yr-7yr-10yr or whatever written into it and they can opt to stay. It also means the Billionaire can end the contract and go find a younger model. So it’s not so much about lasting a lifetime, they have an arrangement basically.
