I dont know what to do

I am so so so unhappy in my marriage. My husband and I basically can't stand each other and all we do is fight. We have a 9 month old baby boy and I dont think it's right for us to continuously argue and fight all the time. I want to leave but we just bought a house a few months ago and I'm a stay at home mom with no job. I can't afford to live on my own with a baby. I just feel stuck and alone and depressed and I dont know what to do :( I'm done.

Oh and here's an update:

I asked him this morning to take the baby real quick because I was about to pee my pants. His response "Put him on your lap. I'm buying movie tickets." Guys I can't. I just can't. I hate him.
