He almost killed us!!!!

It's been small stages of diferent changes. Smart mouth. Yelling. Cursing. To pushing or threats. He had started snorting powder and he denied it but I noticed. At the lake he talked about doing better as a man. And he stepped away to the car. When he got back he immediately started drama. The cursing fussing. While 9. I was so scared I begged to go home. Once we made it the fight increased. 12:30pm my son rises from his sleep from the noise he come to ask what was wrong and he turned on him choking the breath out of my child. None stop. For the life of me I could not get him off of him. During him choking him he hawked and spit directly in my son's face. Calling him bitches and everything but a child of god. I managed to free my son enough to break free. And we called the cops. He is on parole sentence of 12years suspended any trouble will send him to prison 12 years fla. I pressed charges when the cops came. But now I feel so bad so scared because although I know he needs help I don't wanna be the one that sends him to jail. He need help. And my son will never forget what he did to him. Still today police havnt found him. He has no remorse. No apology to my son. I have not heard it seen him. How crazy is that from a 10 year marriage? I feel so messed up!!! Ain't nobody been thru worst then me
