Marriage advice

I just want some advice on how to handle this In the most mature and respectful way. I love my husband and he truly is a good husband, and so leaving him is not an option. I just don’t know how to approach this situation or ask for help and really get him to stick to it. My husband does not help much around the house or with kids. My schedule is up at 6-7 am (but I have a 8 week old baby so I am up multiple times in the night breastfeeding), then I get up with my 19 month old, I am cleaning from the moment I get up to the moment my daughter goes to sleep around 8-9 pm. I do everything from laundry, cooking and cleaning. I stay at home so I do feel the majority of it should be done by me and I do it with no complaints. I cook all the meals and even meal prep his lunches because he’s dieting right now. When I mean I clean everyday, there is laundry done every day, I cloth diaper also to save money because I am a SAHM so I try to save anywhere I can, I do the dishes at least once or twice a day, at night the sink is always empty, I don’t want to imply my house is spotless because it’s not, but it’s pretty close and I do that because my husband gets overwhelmed by clutter so I do whatever I can to make sure he comes home to a clutter free home and he can help me with out youngest and spend time with me. Here’s where the problem is this is his schedule he gets up at 10-10:30 am and leaves by 10:45 am for work and gets off work at 8 but goes to the gym and doesn’t return home from work until 10-10:30 pm most week days he goes to the gym 4-5 times a week. He comes home showers and eats dinner and stays up to play video games till 2-3 am. Now he does get up in the night if my 19 month old gets up because I Cosleep with my 8 week old and he’s basically on my breast all night. So the problem is I’m the morning he is never up to help and when he gets home things like the trash which he previously agreed to be in charge of taking out he doesn’t. He waits till I go to take it out because it’s over pulling or just doesn’t do it. Therefore I have to during the day. He tells me he will hear the kids screaming in the morning at me and he will stay in the room. I’m overwhelmed and tired and need help addressing this. Also I’ve asked for help in the morning and he has done it and will do it for about a couple days or a week and then falls back off. I will say after my C-section with my youngest for the first month he got up with my older child in the mornings and he would normally do the dishes and take the trash out but he went back to work at 6 weeks post partum. So two weeks of everything on me again and I’m losing it alittle.
