Help. (Violent)

(The weird kind of wavy marks in the second photo are from my socks)

EDITED: I'm sorry, I want to remain anonymous so I'm not going to comment. I can't go to the police, he keeps saying I started it. I was sitting on the bed on my iPad, he wanted to use my computer then grabbed me when I said I'd get it when I was done with what I was doing. I tried fighting him off of me and yes, I admit I kicked him a few times. Now he's saying I started it. My arm and both hands were scratched (still got slight marks, but I got photos of them all) and my ankle is bruised. He says I pulled his hair out and is blaming me for cuts on his nose (which were caused by the nosepad on his glasses a while back). He's very narcissistic and knows how to manipulate people into getting his own way. He's already got his mom, my MIL, believing that it was me who started it. He decided to text her after it happened, and said he was 'considering divorce' and that he 'doesn't trust me anymore'. I thought she liked me but then she said loads of horrible things about me. I'm scared of what could happen. My BIL is the only one who trusts me, but he knows what my husband is like so he's playing 'mediator' while trying to keep me safe. I don't know what to do anymore.
