Your feelings are valid but the opposite view is also perfectly reasonable.

I would be proud of my wife for being so successful (or, I would have been while I was still alive).

There’s no shame in being in your partner’s shadow. It should be a source of pride and enjoyment instead.

To take an extreme example, look at Dolly Parton and her completely not-a-celebrity husband. Do you think that Dolly Parton’s husband is embarrassed that he isn’t famous or that he’s just thrilled to be married to Dolly Parton?
