@Sydney0101 I don't know what culture you come from, but it seems to me quite often that when this excuse is rolled out, in many many cases, only PART of whatever was/is the cultural norm is present. Inevitably, of course, it's the part that works for the man.
So, for example, while my family is not particularly religious, I grew up surrounded by lots of pretty hardcore christians. I have lost count of the number of weddings I have attended where not only is "obey" included in the vows, but there's usually some reading or homily about what this means. And it's all about yes, man is head of the house blah blah, but it's his job to care for and look out for his wife and children etc.... But in real life, in my experience, the grooms really only want the "obey" part and the traditional split of labour so that the women takes on all the household chores. The other parts are missing - the part where he earns enough so that she doesn't have to; the part where he is expected to spend time with his children to impart all those things only a "man" can teach; the part where because he's in charge he takes on all kinds of responsibilities. These couples who are my generation don't seem to see how incredibly different their own childhood's were - eg in our community, at least half my friends' mothers were SAHM but certainly, I can't comment on total financial stuff but there was always money for good haircuts, nice clothing etc etc; certain things were absolutely expected to be the dads who did them - late night lift clubs, oversight and engagement with all sporting activities, any "dirty/heavy" jobs etc. My grandmother told me that she was horrified when my grandmother died to discover that he'd had significantly less spending money than him throughout their lives - because he saw it as his job to take on the "big expenses" and her earnings were "pin money".
Needless to say, I have very little time for many of the men I grew up with and I suspect their (traditional) fathers are as horrified by them as I am.
And of course, while my little liberal heart finds this hard, there are also some cultures that really just do treat women terribly in every way. So if your culture is one of those, then appreciate it will be that much harder to extricate yourself.
