abusive husband

I have decided to leave my husband. After we went out for drinks for his bday he enemies up taking advantage of me while I was to drunk to stand up for myself. I have also come to realize he is emotionally abusing me. I looked up the characteristics of an emotionally abused person and they all fit me to a T. I am so scared to leave though. My family is supportive but my mom just keeps asking if I'm sure or if I want to work it out. I'm pretty sure my husband will not stop treating me like this. It has been like this for 4 years. I'm done. I also hate that my oldest son told me he doesn't like daddy because he yells. Not. Okay. At. All.
