You said your wife is Japanese right or at least that she moved here from Japan? I feel like this HAS to be something you already know, but just in case... It maybe a bit stereotypical, but I'll go out on a limb and say she doesn't actually think a "good father" is someone who's great at taking care of the kids and cooking. I mean, expecting the dad to be the breadwinner is pretty universal, but in Japan, where a guy is defined by his job/company? Imo, none of the other stuff actually matters, she's lost respect for you because you aren't providing. That doesn't mean it's easy to fix, but trying to fix it by doing more chores is exactly the opposite of what will help the problem. If you want to save your marriage, fuck your pride, go get 2 minimum wage jobs, and be the best minimum wage employee ever until you upgrade.
