I think the key factor was that she had some fame prior and expected that to continue but it was usurped by her husband. For me, having a spouse who became famous is not much different from marrying a famous person. Sure, there are some lifestyle changes if there's a risk of paparazzi, but I wouldn't expect any attention on me because there had never been any attention on me.
With her, it's a bit different because she had a career and that career has to take a bit of a backseat to his career. His fame interferes in it. I don't expect any fame in my own right, so I'm not going to be upset at the lack of attention I'd receive.
