jf02: Them working is at best a b’dieved to be avoided if at all possible. That it’s done is out of unfortunate necessity. About mothers who are the only income in the family, I’m not keen about that setup. But if done for the benefit of her husband’s Limud Torah then it is an accepted trade-off. And it is far from being newly fangled arrangement. It surely wasn’t as prevalent in previous generations, due to the economic inaccessibility of being able for most families, but it’s greater popularity in our generation is a positive attribute.
That something is not the mesorah or traditional thing to do is neither silly nor weak as a reasoning for it to remain that way. It is in fact a strong argument. You should train yourself, even if it is difficult, to enjoy and treasure the day watching the menfolk dancing joyously with the Torah.
