I think my boyfriend tried to kill me

Trigger warning for abuse

Me and my boyfriend got into an argument last night because he was mad I woke him up. I woke him up when he was sleeping on the couch to tell him I was going upstairs to go to sleep so he didn’t freak out when he woke up and I was gone. He started screaming at me so I went outside to get away from him and just take a breath and he dragged me back in. I started yelling for help as he was throwing me around and got me on the ground and covered both my nose and my mouth. I couldn’t breathe and pried his hands off my face over and over and every time he would immediately cover my nose and mouth up again with the other hand. I kept trying to tell him if he stopped suffocating me I would be quiet but i couldn’t even get more than a word or two out. I seriously felt like I was going to pass out and he was going to kill me and he wouldn’t even care. After we stopped arguing he said he was covering my mouth to keep me quiet so he wouldn’t get arrested but if that was why, then why was he covering up my nose too? Why was he trying to stop me from breathing? I’ve been abused before but this really messed me up because I really believed he was going to kill me. I don’t think it’s enough to get him arrested though because I don’t have proof any of this happened. I’m back home with my parents now. I guess I’m just venting. Thank you to anyone that listened
