Kittywits, thanks for the insight into your life.
It fascinates me because it describes my parents' marriage and the sort of marriages that I get to see in my place of work (City). But whilst my parents' marriage was/is not a happy one - my mother felt very lonely - you and dh seem to have worked it out.
I don't claim to know Mr Kittywits but think I can just about visualise the sort of man your dh is - feel free to correct me. I admire their drive, brains, presence, command - always had a weakness for boffin-like types. Unfortunately, they also tend to be the sort who think working mothers are a contradiction in terms (cue eyeballs rolling) and, quoting from real life, joke whether it is more expensive to hire a woman or to marry her. I can't imagine them helping out an awful lot at home.
I do note that Mr Kittywits does not work in that kind of environment, chose to work from home with some semblance of a family life (no nappies nor being a birth partner notwithstanding). So I don't consider him the stereotypical City-type.
But but ... it is a lot of pressure for a man to be so clearly slotted into the role of sole provider. The area that Mr K works in is, I believe, financially rewarding but very volatile and risky. Investment is not a science, and even the brightest/hardestworking cannot predict the markets. I agree that you don't have to consider the worst case scenarios, but I believe Mr K being prudent would have an exit strategy.
So where is all this leading?
The division of labour works well, for now and possibly until Mr K is ready to retire. But if a person's identity is so tied up in his earning power and success (with his partner reinforcing this), it has a potential toll on self-worth, even when the going is good. Needless to say, if the going gets rough, I don't think it would be a simple case of Mr K happily re-tooling into a nappy-changing birth partner.
That is the danger of polarised roles. Apart from division of labour, I think balance is more important. Hey, I am not saying I don't envy you, if only because you can spend so much time posting on mn . But sometimes, it could be good to try and step into the other person's shoes and try them out a bit.
