Hes gone

So I know I've made posts asking for advice and if I should leave my husband. I always made excuses on why I should stay. I finally realized that his issues aren't because of me and he wont change until he's ready... And he will never be ready. On November 12, I had our baby boy. I was so overly happy. I saw how he was with his niece and nephew, so I was excited for our own son to get that kind of love. I quickly realized I was wrong. From the moment we got home, I had to beg and cry for him to help out in any way. Whether it was with the baby or just cleaning. Then I noticed his whole demeanor change. He got more controlling. Refusing to let me talk to people, not let me go out without him, I couldn't have friends over without him there, wouldn't let me talk to my parents unless it was monitored. Well I was getting fed up. After the overdose incident in the L&D unit, I told him if he fucked up in any way again, I was leaving. WITH OUR SON. December 1 he decided to fuck up. For 3 days prior, he was buying and using drugs. He denied it, but I've known this man for years... He was high. Then on December 1, he got high and drunk. Refusing to let me drive home. Stumbling around the house, passing out, being a bully. I told him enough was enough and I wanted him out. Well he wouldn't. He made me block all my old friends who told me he wasn't good for me. I decided I missed them. I told him I did and begged him to help with our son. He refused and told me roll block everyone again and give him my phone. When I refused he punched me and almost broke my arm and threatened our son. He used to do this all the time along with choking me and threatening to kill me. I called the cops and he's still in jail, being revocated. I moved back home with my parents and raising my son as a 21 year old single mom. I'm filing for divorce and full custody. I'm done with the bs and making excuses for a boy who just doesn't care. And I won't let my son think that behavior is okay. It's hard and lonely, but we are much happier. I'm doing my best to give my son the most amazing life possible
