My husband laid hands on me for the first time ever..

Long post:

We were mad previously before he started to choke me. We came back from my goddaughters 2nd birthday party. My husband was drinking throughout the whole party when we arrived home he slammed my car door and I told him please don’t slam my door. He took our dog out and I locked the door just to be funny and told him he was going to sleep outside. He started laughing and I opened the door to my dog and when I was about to close it he opened it and I started laughing. As I was walking away he grabbed me and out of nowhere he started choking me I kept pushing him away and he started to hold me tighter and tighter. I managed to push him away and told him to never put his hands on me again. Idk what to do. Do I leave? Call the cops? I need help!
