In my SAHM years, I neve, ever saw muself as a 'Kept' woman.
I always saw the family unit as just that - a unit to which we all made our contribution. - we had children they needed caring and nurturing, we could have paid for it, or i could do it.
In fact in my case, my DH's work, especially when DC were small, required a lot of travelling often at a few hours notice and for indefinite lengths of time. As a result I was the CEO of the company, or close to being a single mother at times. I cared for the family, looked after the finances, managed everything from holidays to buying and selling property.
I earned my keep, even if I did not earn money. We always saw the income coming into the family as our income.
This continued after I returned to work. If I had put my career and career progression first, I could have gone higher, achieved more, including more pay, but I went far enough to earn a comfortable salary and have a good enough occupational pension and I have never regretted choosing to earn less and have more time at home.
It probably meant my DH could earn more, because he had an efficient adminstration he could trust at home. My DiL has made similar decisions.
