You forgot to mention child support which is for up to 18 years. Also, nothing stops the woman from having a career, especially if she cooperatively shares 50/50 custody, but often they prefer aiming for nearly 100% custody because it increases their child support payments, and then still have the option to cry victim that they’re a single mother despite getting thousands of dollars a month and they’re actively preventing the father from being involved with the kids. Happens a lot.

As for a stay at home mom who doesn’t get divorced, she doesn’t need to be entirely stay at home for all 18 years.. kids go to school at 5 and can go to after school programs if necessary while she works. A couple years before that if the kids are in pre school she could get a degree or masters degree or work part time. So the career gap could be minimized.

Child support is until the kids become independent not 18 years, which I don’t know if you’ve checked these days but kids stay at home indeterminately

Probably depends on the state, but last time I checked it was until 18 or high school graduation, but not later than 19, in the state I’m familiar with.

In my state Alimony is neither temporary nor fixed, depending on the length of the marriage.

Western Marriage is a contract where one party is rewarded for breaking the terms. The low marriage rates of Millennials / Elder Z [1] are indicative of this new world order. It isn't just "because men!!".
