Why are we even together anymore?

I can't stand my husband. We have been together a little over 4 years, married about 6 months, and we have a 10 month old daughter.
I always worked before having a baby, but once she was born we agreed I would be a stay at home mom. SAHM-not a stay at home servant.
He never helps me around the house. Doesn't help with dishes, cleaning, laundry, cooking, doesn't even fucking pick up after himself, and he won't make himself a lunch if I don't make one. All he does is work his 40 hour week and come home.
He doesn't help with the baby. Doesn't feed her, bathe her, wake up with her, dress her, play with her...nothing!
Today I was trying to install cabinet locks. After 4 months of asking him to bring home his tools from work to do it, I gave up and went and got tools to do to myself. He couldn't even watch her while I did that.
If I walk away and she cries he just sits there on the couch, doesn't get up to comfort his child.
I'm so ducking sick of having no help. I don't want more kids with him. I'm not having another child-ever. Why am I even with him? 
I don't enjoy being with him. I resent his laziness so much I don't even want to have sex with him anymore.
I just don't fucking want to do this. Period. I don't.
