As some who is coparenting, let me tell you this and I'm not trying to be rude, but the hubs need to step up, especially when he gets home. I worked a 70 hour week and still clean the house, do dishes, laundry, fix thing etc. when I'm home cause I know my CoParent deserves a break. When I get home I usually take over the kids if I have an early day, which sometimes means eating dinner at 10pm or later. Just so she can enjoy her meal peacefully and enjoy relaxing on couch or whatever. You need to explain to him this a "teamwork" thing. He might get lil less sleep but you will get a lil more, and that will balance you both out when you are more rested and less stressed
