I am equal to my OH, as in same or similar job. When he was promoted and started being on a higher wage it coincided with me getting more overtime and teaching outside of work, so he never earned more than me.
I hate housework so checked out of that, and employed a cleaner! I did the washing, we shared the ironing and he did most of the shopping and cooking.
We both retired but I now work part time, so he does the cleaning, washing, ironing, shopping and cooking.
BUT – I do know a couple where she has a lesser paid job. She did all the child raising though, cleaning, washing and cooking. She is very happy, as is he. Each to their own I guess.
