What you describe was how things were weekdays. Weekends, my huband shared the childcare 50/50 and did a little housework as well. My rage was when he came home and did nothing because he said he was tired - this from a guy who did no nights with DS whatsoever that first year - our marriage was under serious strain.
These days, he leaves the house at 7 some days and isn't home till 11. It would be unreasonable to expect anything but sleep for him those days. When he has days off, he gets up with DS, plays with him, feeds him, loads dishwasher and washing machine. He does no other housework but the fact is, he is almost wholly in charge of DS those days so that doesn't bother me.
A guy who expects to work 35 hours a week while you work 175 is taking the godwaful and almighty piss. My husband works 60 some weeks and still does more than yours. And frankly, that first year, which I still resent, he did more.
I may add that I don't even know what days are bin days. My husband has done that since we were married. And for the father of a 5 month old to expect to have weekends off when you have been 24/5 in the week is totally disgusting, IMO. When exactly do you get a break? He at least has a lunch hour, as I pointed out to my husband when demanding a 5-/5- weekend split.
I will say though, that even now, when things are so much better, he still looks on my time with DS as available for me to sort all kinds of other things, because I'm not at work - while his time with DS is hard work and necessarily means he can't possibly do anything else. I think that's common with the women I know's partners after babies arrive. Gender roles sharply emerge in even previously egalitarian relationships.
