Help with communication

I am having issues with being open and honest about my struggle with burn out at home. I work upwards of 60-80 hours a week. Wife stays home with two toddlers. One with ASD. My wife was diagnosed with Autism level 1 a couple years ago as well. We have been together 8 years. We have two children, 3M, and a 4F. With this being said, I work A LOT as a commercial service plumber. That’s very long hours, less sleep, and trying to maintain a household. My wife struggled with staying on task, finding things to do that need doing, and pushing herself to do the mundane day in and day out stuff that requires a stay at home mother. The days of old have passed. The ol’,” I go to work 50 hours a week, and you stay home and raise the kids, cook us dinner everyday by 5:30. Clean the house. Do the laundry. Keep the house in order” are dead to the forwarding feminist movement. My wife needed someone special to scoop her up in this life cause she struggles so much with the day to day. By that I mean… I get home, usually my son has thrashed the house or his play areas. I start helping tidy and clean, make beds if she didn’t remember, I usually start dinner as well. I cook cause before I was a plumber, I was a cook in many high end restaurants. I was a chef for 8 years before plumbing. She struggled with boiling eggs and watching the kids at the same time. And that’s ok. I’m a better cook. She usually cleans . When I’m done with dinner, I start the bath by 7 and both the kids get baths that I give them. I get my daughter out and braid her hair cause I love it, and usually put her down first. Then she usually helps with my son. I usually do a load of laundry once a week in there to. Then I’ll shower, and usually, just about everyday we are intimate, and I go back to work about 8/830 till 2/3 am, get up at 8, and do it again…how can I avoid burn out man? I am so madly in love with my wife it’s insane. 8 years in and I can’t keep my hands off her. Like today I got half the day off early, and we ended up being intimate 3 times. I don’t mind most days or weeks that this carries on. But some days sex isn’t enough to blow off some steam. My job is so high demand and stressful cause I am the most experienced guy at our company of 30 plumbers. How can I avoid the feeling of burn out? How do I tell her somedays I need more help? Thanks so much if you took the time to read and reply.
