Marriage is ending, what do I do?

I don’t know what to do, we have been married for only six months, we bought a house and we have a giant mortgage now. But ever since we got married it’s like he changed, and he hates everything about me. He swears at me and punches doors and slams them, he yells at me a lot. We have talked about divorce before out of anger but tonight he said he wanted a divorce because I’m never going to change, because I can’t communicate. I don’t know how I am suppose to communicate back when all he does is bash me, and gets mad at me whenever I state my opinion. So yeah I guess it’s true I don’t communicate anymore. I’m all for giving people more chances but he hates me for “holding things over his head” but how do I do that when he does the same things consistently? I’m not saying he’s the only one to blame because I’ve made mistakes too, but there is a way to be wrong and still not be verbally abusive to your spouse, and there is a respectful way to disagree. It’s just at the point where I’m having trouble going to work, I’m worried about coming home but I do because we have a dog and a cat to care for. (no kids). I’m a nurse and yes I do admit I’ve been picking up hours to not have to be at home as much, and today I came home and he says that there’s nothing I do everyday that is special which really hurt because I worked really hard in school. I did some research and it looks like I’m not going to be able to file for anything until after a year. Even then, I don’t know how I’m going to afford a divorce, our only shared asset is the house but we both together barely make ends meet because our mortgage is expensive. If we have to sell the house in divorce, I don’t know how I would pay my half of that and still pay for an apartment. I guess what I’m asking, is if anyone has gone through this or they can offer some advice? I know I need to speak to an attorney to see how the heck this would work, but I guess I just wanted to see if anyone had any advice. I’m going to try and make this work with him but I guess I just wanted some security if things do get worse to the point I have to leave ASAP.

Sorry for the book
