Ask her how she would solve the issues she’s raising, how would she do it better?
It sounds like she wants to be heard, and as your wife that’s going to be a diplomatic affair, and good practice for you on setting boundaries.

onedaywebsite.ca started out doing Wordpress sites for $299 back in 2011. It turns out that going for the cheapest also means the cheapest and heaviest complaining clients. We now charge $5k yearly as a base, but we not only convert static sites over to Jamstack (from wix/wordpress/squarespace) but we help with business and conversion throughout the year (SEO, SEM, optimization). We’ve never advertised in over a decade, it’s all through word of mouth referrals. Entertainingly, our website sucks, but again, we’ve never got a customer through the website yet, but if things ever slow down we’ll likely work on that, “eating our own dog food”…

If you’re offering this value with nothing in return, I commit to not doxxing you – I have a decades long history in privacy (you can look up my name online).
It’s a bit meta, but I’m working on customer discovery & validation service that is above consulting (scalable / aaS) in the same space, which is the biggest bottleneck to business success in my experience as a serial entrepreneur and advisor.

I play in this narrow lane, helping those willing to take action to start their business, working on customer validation, from an idea that has an intention of providing value.
If their goal is to be rich or meet wealthy people, I don’t help this demographic, as it’s not likely to succeed.
