unhappy

I am married with a 2yr old and a 6mo old. I'm no longer in love with my husband. I've been trying to make it work since my first son was born. after I had my oldest my husband turned into a self pitying asshole who doesn't help with anything, almost never gives the kids attention, always talks about how annoying our kids are and how I should be paying more attention to him (which I do but when the kids need me of course imma stop what me and my husband are doing)... basically he just can't stand this family we created together. He's a short tempered jerk who pushes my kids away when they wanna play with him because he is "too tired". I want out but gave no idea how to do it. I quit my job when I was pregnant with my youngest because my husband said he can't handle the kids (well at the time it was just the one kid) alone, he refused to help with housework and cooking and would only feed my son cereal. so I quit to become a full time parent and save our relationship because as you can imagine we argued all the time. so again I'm jobless. have zero family literally because my only family member I have left is out of state. no car. I have nothing but these amazingly beautiful kids that deserve so much better. I'm trying so hard to suck it up for them because I have nowhere to go but my 2yr old is already showing pain from the neglect his father is giving him. I don't know what to do. I need a job of course but have no transportation and no babysitter. I just have no clue how to proceed with anything. Advice?
