How do I get him to help more.

Hi ladies. I'm five months pregnant and my husband won't help out around the house. He says his only job is to work and make money so that i can pay the bills. All he does is sit on his ass and play video games all night when he is home. He doesn't help out on his days off either. He will do two dishes and then sit down saying his feet hurt. He then promises that he will do the rest later and he never does them later. When he cooks he leaves a huge mess and I end up having to clean up after him. How do I get him to help out more? I have tried talking to him and he doesn't seem to listen no matter what I say.
