DH and I used to both have the regular Mon-Fri, 40 hour week. Sunday was the cleaning day, we'd alternate cooking. I was never, ever one to think these were naturally my jobs, I never ironed his clothes (still don't), and was actually a lot more slatternly and lazy about housework than he was.
Then DH quit his job, became a self-employed personal trainer, and most days will be out seeing clients from 7am up to about 9pm. That's a long day! With traveling across London, he doesn't get home until about 10-10.30pm, up again at 5am the next day. He regularly does 6 days a week, sometimes 7. When he is not physically at the gym/seeing clients, he is at home working on building up his business.
I still have my Mon-Fri 40 hour job in the City, but I leave the house at 8am, home for 6.30. I'm now also 5 months pregnant. I do the majority of cleaning/cooking but I have drastically reduced my expectations of the amount of cleaning we actually need!
I really struggled in the beginning with this idea that I had a full time job, and was doing almost everything else myself. Until I just actually started seeing my husband physically and mentally exhausted and I just thought - it's not about feminism, Stepford Wives type behaviour, or perceived domestic equality. I am not going to demand my husband hoovers up every single week because of my worries about becoming a domestic slave. He is working extremely hard. He also has no expectations of me to do these things - he keeps saying we should get a cleaner.
It's about looking after each other. My husband is extremely supportive of me, of everything I do and want to do. He helps me all the time, in so many ways, when he is exhausted and just wants to sit quietly. If I can support my husband in his quest to raise a successful business over the next few years, just by making his life easier by just making sure he has food to eat and clothes to wear - it's no skin off my nose. I finally realised - the actual work is incidental. It is incidental that he is working his arse off outside the home, and I am here doing these domestic chores. We are both contributing to the mutual support we offer each other.
