Divorce while pregnant

I haven't been super happy for awhile. My husband is nice and not abusive but he has no goals and no drive in life. I work 7 days a week to make sure the bills get paid and he works a normal 5 day job at a warehouse where he makes very little money. I don't care about the money. .but he hates his job and always complains. He hated his last job too and only found a new one because he got fired. I have had the conversation multiple times about moving out because I need somebody who is happy with what they do and who has goals. He always promises to change but then I find him on the couch watching TV every single night. He doesnt help pay for much except his half of rent and he never cooks or runs errands and he never wants to do anything but sit and watch TV.

Now I'm pregnant. And I am thinking for 2 and I don't know if I can do this with him. Does anyone have advice?
