Husband treats me like crap because he knows I won't leave

We just had a baby and he treats me like crap. He goes out to his friends everyday which would be fine I guess but he lies about it and leaves for hours. Today he left saying he wasn't going to be gone for hours, it's been around 4. I told him before I left don't leave for long because I was hungry. He has our money, our car, and I'm home alone with baby. I reminded him I was hungry over an hour ago and his response was "ok a few more fights". He's playing a video game and of course that is more important than me eating. He does stuff like this all the time. Any time I'm unhappy with something he does, he continues to do it because he sees that I don't leave him and knows I won't and takes advantage of that. I'm miserable.
