Diana worked her entire adult life up until we moved to Seattle. Since my income was/is adequate, she decided to be a stay-at-home mom for an indefinite amount of time, and I'm 100% behind her. While one might consider this "traditional" gender roles, there's nothing more to read into.
That's why I get annoyed when someone suggests on Facebook that she has to check with me to buy something, or otherwise suggest some kind of authority. It annoys me because it implies that I'm some kind of '50s breadwinner dickweed archetype (get me a beer, woman!), and that she's the little obedient homemaker. What year is this?
I trust Diana to use her own judgement and do whatever she thinks is right. It doesn't matter where the money is coming from. That's just how we roll. I'm sorry that some people have relationships that are toxic, not respectful, or otherwise shitty, but don't project that on to us.
