Thank God (or whoever) that my DH didn't wish to have "his own money" cos there would have been none left at the end of the week, despite him being pretty well paid! I managed it all for the benefit of us all.
Mumsnet is, sadly, full of women whose marriages have failed so the need to have your own finances has proved to be paramount. In 1970 it wasn't the norm. "Career Women" - as my DM called me when I hadn't presented her with a grandchild by the age of 25 - were still something of a novelty.
I married at 20 having left school at 16, despite being top of the class. It was expected in working-class families. After marrying I decided to train as an Accountant and it took 7 years, when I then had my first DD. I was in a very good job as Chief Accountant in an International Advertising Agency (think "A secure home for your money with Bradford and Bingley" and the Dulux Dog). I never intended to go back into the job but I managed to do two evenings a week teaching Accounting an Night School to middle-aged women who wished to get into the job market again. I loved it. When DH came home from work he was handed the baby and off I went!
When DD2 came along we were short of bedrooms so we moved, but it was a scary mortgage for us. I remember saying that we would not be able to afford to replace any of the carpets or eat meat again!! But I started to take on private clients and when the girls were at playschool/primary school and other mums did part-time work we took it in turns to have 4 kiddies once a week. We also did favours in picking them up from school.
That was my working life till my youngest was 11. And by then, we DID have new carpets and DID afford to eat meat, and even had an extension built.
Had we based our lives on the assumption that we would split up, I am certain that our girls would not be as stable, loving and successful as they are. But then, had my marriage failed (there is something to be said for sticking it out rather than ditching your partner at the first argument), I would have lived comfortably in a flat rather than my 5-bed detached, and got on with it.
Of course I believe that people should make their own choices in life and nobody has the perfect plan. Both my DDs are the chief breadwinners in their marriages (or were, cos my eldest has just been served with her redundancy notice). Only the eldest has children (now teens) and though they went to nursery it wasn't full time. Both sets of GPs had them a day each, for some years DD only worked 4 days a week, later it was term time only, it all worked very well.
But each to their own, quite rightly.
