Just because you decide to split things like this doesn’t mean it’s sexist.

I earnt a lot more than my wife did and we jointly decided she would stay at home for a few years and I would throw myself into work to cover the family income.

I would have been more than happy to switch roles if the shoe was on the other foot!

Husband? Usually it is a wife who decides to stay at home and makes most decisions! Women control like 80% of purchasing power, most advertisement targets them!
