Am I eligible for spousal maintenance? He was verbally and physically abusive forcing me to leave him.

We married in 2006. He assaulted me 4 times in our marriage. He's threatened to kill me and my unborn child. I have an order of protection against him and finally left. I've lived in 3 domestic violence shelters since leaving. My husband was financially supporting me when I left. We were together for a little less than two years when I left him. Prior to officially leaving, I decided to live elsewhere in hopes that he'd get his self together. But he didn't. We sought counseling, but he would attend it drunk. Between that and the threats and abuse, I had to leave for the safety of myself and my children. I'm considering filing for spousal support. Is that an option for me?
