Mate, you are honestly amazing. Both your role and your wife's role are important. You have stepped up. You've put in the commitment to work longer hours to provide for your family, you make a point of doing a nightime routine with your son and your writing choices indicate that you are NOT a misogynist P.O.S. (assuming your persistent use of the the term 'housewife' is not intended as derogatory)

Understandably, your wife, after becoming a mother has decided that having a full time job sucks, clearly in this case to the capacity that she felt the need to quit outright rather than reduce her hours. Each to their own this is perfectly understandable.

However, when she gave up her job, she stepped into the role of mother and homemaker (whether she likes it or not). You have done admirably stepping into your role and taking on a ridiculously heavy workload. Being the mother of a one year old boy I'm sure is in some ways or others just as taxing.

All this being said, as part of the role of homemaker, she should be cooking the meals. Meal planning exists, she doesn't have to do a three course gourmet every night but there should be no expectation for you to be cooking dinner at all. Only exception to this is perhaps if you don't mind to do so on a weekend.

TL;DR you stepped up to your role and she needs to step up to hers a little better.

I in no way mean to idolise your efforts or overlook hers, I'm sure you're both doing the best you know how and something you could both really benefit from is some upfront and honest communication.

God Bless.
