Yeah. Dp leaves the house at 5am gets home 5pm usually. Constant stress as a self employed sub contractor running a small firm.
I work part time doing the admin side of things. I do 95% of the housework and childcare (13,4). I do however expect dp to do any ironing he wants doing as I don't iron. And he cooks our meal on a saturday evening. He will also do any childcare if I have an.appointment or want a few hours off. He washes his own dishes and any others that want doing over the weekend.
And if crumbs on the floor were annoying him he knows where the hoover or dustpan is.
Working 60 hours a week and being in possession of a penis doesnt mean that he gets to opt out of the mundane boring tasks of parenting and being a family. Some days I shit miracles. I work for a few hours, clean the house, do any chores, look after ds, see to the animals, cook a healthy and delicious meal and have a cold beer waiting for dp when he walks in with a smile on my face.
Some days he walks into a shithole, kids arguing, me looking and feeling a mess and general chaos.
Sometimes he is stressed to the max. Sometimes he is as happy as a dog with 2 dicks. But one thing he would never do is tell me we are swapping roles because I can't earn enough to maintain our current lifestyle. And we made a decision that I would be part time and him full time when ds was tiny.
Had I gone back to work full time when ds was little my career might be in a different place but we sacrificed my earning potential based on joint decisions we made.
So for your dh to change his mind is not only insultings it's incredibly selfish. It might be a reaction to some specific stress but he can't use you working pt as a stick to beat you with because he is finding work tough right now.
He has to suck it up for now. You work out a plan together that is right for everyone in the family and go from there. If you decided being a sahm was too stressful and wanted to Jack it all in he would laugh at you I bet.
