I think all partnerships/marriages make compromises thiugh about what is best for them and what works for them. When I didn't work I paid for food, clothes, day to day for the DC etc and kept a note and receipts and my DH gave me a cheque at the end of the month. We never qyibbled or questioned because we have a similar outlook over expenses. DH paid and continues to pay all bills - everything. When I went back to work he started to give me a monthly supermarket allowance and I started to pay for clothes for me and the DC, my petrol and gradually took on things like instrumental lessons, phone contracts, dentist bills, etc. We have never had a joint account.
I work locally, DH commutes (30/40 mins each way). DH is out of the house for 12-14 hours; I am out for about 9-10. I do more domestic stuff because I don't work as hard at paid work but that means combined I work about an 11-12 hour day.
I was at home until dd was 5, part-time until she was 7. Then we had au-pairs for 4/5 years and that worked for us. When dd was about 12 the au-pairs stopped because both DC decided they were too big. That year dd got home at 4.15 and her bro was usually home by 5ish. I made a point of leaving work by about 5.15 that year. Now I'm usually home at 6.30. DS has left home, DD is busy with after school clubs until 6.30ish three times a week. If I didn't work I think I would be lonely.
It works for us and has worked well and I feel we have combined obligations together and also I think we have also maximised our family assets optimally. Some of it was luck, some of it was planning. We were very lucky to have bright, relatively easy and well balanced DC. Had that not been the case life would have been diffrent.
For the poster who said upthread that she suffered abuse due to working parents I am deeply sorry that happened and I hope you are in a better place now.
But, just one final thing: what really irks me is when full time mothers/wives tell me how stressed they are because of getting things ready for christmas or holidays. That's where I feel an urge to say, "why are you behind, why can't you get yourself organised, if I can get the xmas cards written and sent by early decembern why the flip can't you?
