I used to have a SAHD DP for a while and he did very little. He used to feed the children on home made food that I had made and put in the freezer. he didn't clean or tidy or change sheets or anything like that. I never once had dinner cooked for me. Not once.
I find it very sad, upsetting and exhausting, but didn't know how to say anything about it because he flies off the handle at perceived criticism and amps it all up implying I have said about 500% of what i have actually said.
so if I said something like "it would be nice when you make dinner if you were to make enough sometimes to put some aside for me in the evenings" it would turn into him screaming at me for expecting him to be some kind of kitchen slave, turning out 4 course meals while the children cry unregarded.
I could never tell him anything about what wasn't working for me or how unsupported I felt having all this stuff pile up for me at the weekends, because it would just turn into this diatribe about "I was never there" (because I was working - I never went out for fun) and how oppressed he was. I get it, life with 2 small kids is hard - I did a year's maternity leave with the baby and a toddler immediately before I handed them over to him - so I know how it was. But I tidied up after us and had a dinner on the table for him every night - even with a newborn.
I gave up. I was so unhappy that my sole objective was to put up with the situation till he got back into work so that if / when we split, he couldn't pull some "prime carer" shit on me. I thought: maybe I can address this in the future, but if I try now and this relationship breaks down irretrievably, then I lose my kids.
that was about 4 years ago. He's been working for about 3 years now, still pissed off with me for being an inadequate domestic appliance because of the amount of time I spend out of the house, and we are splitting. It's going to be shared residency, I think.
