Wow this whole thread is so bigoted towards SAHW&Ms. What, we are backwards and have low self esteem because we would rather cook/clean/raise children than have a job working for a different man at a company and then maybe paying someone else to be mum/cleaner?
If you both want to/have to work and you decide to have a roughly even split of household chores then that's up to you and your partner. But I'm happily married, "unemployed" (housewife), expecting our first baby next year and taking on the majority of the household cleaning.
My husband will do heavy lifting in the garden, help me with major clean outs, wash pots and pans roughly half the time (most of our other stuff goes in the dishwasher) and does a fair amount of cooking because he is Italian and frankly loves it. However, I do all the laundry (my husband literally couldn't), vacuuming, dusting, cleaning, scrubbing, baking bread, organising, tidying, bedding, food shopping, etc etc etc... and honestly I think that my husband does too much because he already works all day! His "job" is that he goes to work, works very hard, and earns the money to pay for us to live. My "job" is looking after the house and will eventually also be raising the kids - that's a more than agreeable trade for me, and if any of you think that's to be looked down upon and judged then I honestly don't even know what to say.
If anyone reads this and thinks I'm being too harsh then either I'm not talking to you or you need to really have a look at the kind of things you're saying and assuming about the women in these relationships and situations and see how judgemental your language is.
P.S. there are valid situations where a woman is unhappy and the man is not pulling his weight - I just think that simplifying this down to "who does the chores" is an inadequate way to analyse this. A healthy relationship should have a balance but that won't always mean 50/50 splits. 50/50 can be (but are not necessarily) unhealthy because it encourages score keeping and unhealthy competition and grudges in some couples: "I did x so you have to do y otherwise it's not fair".
Final thoughts: focus on your own relationships and making them happy and healthy (however that looks for you) and don't try to sneer at someone else's just because you wouldn't like it. I have immense respect for a woman who works and has a 50/50 relationship with her husband, so long as they are both happy and consenting to that style of relationship. In return, I don't expect judgement from that woman just because I'm not living the way she would live herself.
