Today I was arrested because my husband scraped his elbow

I believe the officer took me in because of what could’ve happened to me. My husband was screaming at me so loud and hard that he was spitting in my face. I was sitting in a chair and he was pushing his body into me. Which was making the chair, bounce off the wall. I put my arms up, trying to push him away from me. He’s tall 6’1” and bigger than me. I couldn’t get them off of me I couldn’t get them away from me. I just kept my hands up, I close my eyes. Then all the sudden the weight was lifted and I opened my eyes to see my husband doing a fake fall to the floor. He looked at me and said look what you did! Look what you did! I was in tears and shaking. I called 911 immediately. He went upstairs, and then came back down and sat on the stairs and said look at you look what you did look what you did, I was afraid he was going to come after me again. I screamed to stay away from me. The 911 operator told me to lock myself in a room, so I locked myself in my daughters bathroom. I stayed there until the officers came. The officers talked to him first since I was in the floor below. I couldn’t hear what he was saying. Then the officers came downstairs for me. I came out still crying and shaking. They asked me what happened and I told them everything. They said because he had a scrape on his elbow that it was second-degree assault and I was being arrested. I’ve never been arrested. I’m an elementary school teacher. I don’t even spank my children, and now because I was trying to protect myself, I got arrested. I can’t go back to my house. I have a daughter who is 17 and 18. They weren’t at the house at the time, but they were able to go and get some of my stuff. I’m staying in a hotel room tonight but I don’t know where I’ll be tomorrow. My husband has managed to isolate me from my family and friends. They all live about three hours away. I called my mom for the first time in years. She was able to give me a lot of great advice, but I still don’t know what to do. I feel so lost, I’m worried about my job, but I’m worried about where I’m going to stay tomorrow night. Someone please tell me what to do next.
