Sorry this is a longer message:
In my case my husband and I met at 14, and got together at about 18. His mother (who struggles with mental illness and hates him and all other men, loves her daughters unless they kick up a fuss then she might flip and everything might be their fault) kicked him out of their extremely low income single parent home at 18 and he had to move in with me and my parents for 2 years until between us we had enough income to rent a small flat. In fact for a couple of years I earned more than he did, but it didn't take long before his drive (and my lack of it) got him better paying roles and we could move out.
We divided chores quite fairly at that time, though he did all the cooking as I had never been taught (he has since taught me) and I did most of the laundry (it didn't take long for him to shrink my favourite jumper and I took on that role lol). Then as we moved through life, he had far more ambition than me and wanted to raise himself up from the poverty he'd lived in before and break the generational cycle, so he worked really hard commuting hours on busses to work long days to progress his career, I worked a local full time job but I hated working, it made me sick... whereas he gets satisfaction out of working and succeeding.
Fast forward to age 26 and we are married and expecting, he's earning a lot (enough that I could stop working entirely this year - I'd been working part time for a few years), he works from home now and does help out with chores I specifically hate (bins, toilets, garden waste) and does the majority of the dog walking (I rarely walk her alone, it's usually we both go or just he does), and he still does a lot of cooking because as I said before he enjoys it.
I don't know if that's what you expected our lives to be like, but I don't think that we are playing into some societal sexist agenda or anything, we just figured out what works for us and we are happy. In fact, since living more traditionally it's the only time that neither of us has not had to be on some form of mental health medication (off meds for about 2 years now and no signs of going back)... I just think we have found our natural roles.
Neither of us is ever unwilling to help the other if they need it. For example I said when I get very pregnant he might need to help me with laundry (specifically carrying the full basket up and down the stairs as we live in a three storey house) but I'm still going to load, add products, supervise and press the buttons etc... and maybe I won't need the help - we won't know until it happens! But he said "yeah obviously lol that's fine"
Perhaps last night in my tiredness I misunderstood what many are really trying to say, and it's about women who are unhappy with the SAHM role and their husbands are lazy and unhelpful and ungrateful. Of course I don't condone that. I suppose I just wanted to show that some or even many SAHM and trad relationships are genuinely happy and that shouldn't be anyone else's business... and it's not very nice for people (not saying necessarily you) to make assumptions about people and the life they've led beforehand based on very little info and a few admittedly heated messages.
I apologise for my attitude before (including the other message this morning), looking back I should've handled myself with more grace and forgiveness and understanding. I hope you have a lovely day.
