My ex was just never made aware of what actually went into the work. His mother was a homemaker, and he's a lovely woman but when I'd visit she wouldn't even let me make my own breakfast. At home, he'd pick up after himself and cook occasionally and maybe sometimes dump some comet in the toilet, but the lion's share of the cooking, yardwork, maintenance and and cleaning fell to me - and he'd say, "I think you just don't see how much I really do around here!" And I think he truly believed he was putting in equal effort because he'd just never had to really do it before. I actually do believe he was trying to make it fair. But when I left, despite having nobody to split the chores with, my time spend doing domestic stuff was cut drastically.
