Husband thinks his job is his only responsibility

When he comes home from work I don’t expect much. He provides everything we have and I am truly grateful for that. But I did not have these kids on my own. He refuses to help with bed time, dinner, breakfast, lunch, playtime. Anything that isn’t exactly what he wants to do, he just doesn’t do it. When he is tired, he just goes to bed. Even when his son(my stepson) is over, if my husband is tired he just disappears. My stepson won’t listen to me half the time and keeps our son wired up half the night. If I ask for any help, you better expect an explosion. He can’t just get up and help like I think a father should. He takes no fatherly responsibility. I didn’t have these kids on my own and one I didn’t have at all. Why do I have to do it on my own? Am I wrong for expecting some sort of input and help in parenting OUR children? If the issue is that he has a job and my job is to take care of the kids then when do I get to “come home” and “take a load off” or “relax”. I will gladly go back to being a working mother if it means he will participate in our kids raising. Should that be what it takes to get input from another parent? All I want is help with our kids. How can I talk to him about this? I’m at a loss and don’t know how to try and bring it up a different way so that he doesn’t get pissed and blow the conversation off again? If I’m going to parent on my own I will be more than happy to get a job and do that part on my own as well. I’m always in the wrong & we can’t discuss how to parent so that we can agree on something that would work for both of us. HELP?!?
