Why does he think I need to do everything just because he is a hard working man and not need to do anything?

I’ve been doing everything including things for him. We have children together. We have been together for almost ten years. He finds me the most convenient person to ask and not only that, there are a lot of times he does not ask, I still ended up having to take care of things because he will not act on it. He does not take any responsibilities or act like an adult. He feels that he is working hard at a full time job to get money and bring it home for our family. Once home, always down to his own timing and space. He does not cook. He does not help around the house. He does not take or come with me to our children’s appointments or school events. He feels that bringing home money is everything. He does not go shopping. It’s me having to do everything. I take care of the house, children, him and I work part time. He said I’m not hard working like he is because he makes the most money. He only pays the half of bills. I have to pay my half besides doing everything. He have problems if I ask him for help with money and would say I’m not independent because I ask for help on paying some bills when I need it. His spare time is to play video games or drawing every day. He does spend time with me and children sometimes maybe for at least one hour.
We had one of these conversations, for example, he wants to find a different job. He wants me to help finding him a different job and apply jobs for him. I said he needs to do it himself. He said, are you my woman or not? If you are my woman, you would do it. I said I will if he is looking into it TOO, he said he does not have time to do it because he’s always working. I said well when you have time playing video games or drawing, you could have used that time to look. He disagreed.
Why does he think that way? Why does he think he does not have to do anything himself because I will?
Even if he wasn’t with me, what would he have done? He said that’s different he would have it done by himself. Help me understand his perspective.
