my boyfriend is not helping enough with the kids

My boyfriend and I have been together for 8 years old. We have 2 kids together, our oldest is 6 and our youngest is 3. Our youngest is special needs so there for i am unable to work because he has so much therapy. My boyfriend works 40 hours a week and i understand thats alot and he is tired but so am i. I get up at 6:30 every morning to make his breakfast, I make a lunch so he can take it with him and then there is a hot meal on the table when he comes home. I also make sure our oldest is up and gets ready for school has breakfast, a snack for school and make sure he gets on the bus. Then i come back from the bus stop clean the house take care of our dogs and make sure our youngest son is ready for therapy (2-5 therapies a day). Then i walk back down to the bus stop and get our oldest off the bus and i make sure he comes home and does he homework. Now when the weekend rolls around i would like a morning to sleep untill 8 am and maybe take a bath and have sometime for myself but he always says "I work all weeklong i need you to take care of the kids and do whatever else needs to be done" Am i wrong for thinking that he needs to help more with the kids and maybe give me sometime to myself???
