My ex narcissist

I started a relationship six years ago with a guy. We started seeing each other, but at first we weren't anything serious. He drank from Monday to Friday, and suddenly we became boyfriend and girlfriend. Everything was going well until we broke up. He was different, and I went to live with him, but then my grandfather passed away, and I had to move back so my grandmother wouldn't be alone since they raised me. From then on, he started behaving badly and strangely towards me. We were on and off, then I got pregnant with my baby, who is four now, and he was happy. But in the middle of the pregnancy, he left me. From the beginning of the relationship, it was infidelity on his part. Then we got back together when my son was born. He showed up the day before the delivery, but I let him be. The same thing happened while I was pregnant; he was seeing his exes, going out, and more. Everything was normal until he threatened me, and I didn't want to hear anything about it. He's always put his family first, and his mother and sister are the reason for this because they fill his head with nonsense. When the restraining order ended, he supposedly forgave me, and we got back together. I went to live with him, and he makes my life miserable. To my children, since I have another daughter with another father, I separated from him. Throughout the pregnancy, I went back and forth, but he made me live at his house, and on weekends he would kick me out and throw everything on the floor. He was always trying to win me over, and I would go back. Then, in those comings and goings, after my son turned three, I got pregnant again. When I told him, he flatly refused and said the child wasn't his, that he wanted DNA testing, that I couldn't be stupid. I went through another pregnancy alone, but I forgave him again. In the midst of all that, before having the baby, my oldest son had a fever for a week, and he didn't show up. When I went to the pool on my birthday, I saw him with another woman. They were touching each other. It hurt me a lot that day; he didn't care. Well, he was still cheating on me with other women because he thought I didn't notice. I had my baby, everything was normal. I helped him buy a car, and he would see me with stitches, walking in the heat from my house to his with the boys in my arms, since my oldest son had... His little leg was broken, and with the stitches, I had to lift him because he wouldn't help me. I took out a loan, I did everything so he'd see me walking and wouldn't care, but when he saw his mom walking, he couldn't be nice and would carry her. Then we fought because of that. I wouldn't let him see the kids because he'd disappear for a week and come back two weeks later as if nothing had happened, asking about them, when the weeks before he hadn't even asked if they were eating. Then his family blamed me, they thought I was crazy because I wouldn't let him see them. I'd go out to the club, and he'd make it impossible for me. His family spied on me, and what's worse, my oldest son's birthday came. I celebrated it all myself, I paid for everything, and he promised to come. But the day before, he fought with me, he was even angry with the boy, and he called him saying he wasn't going to come because he'd fought with me. I stopped talking to him, I couldn't forgive him, but he started messing around again because a few months later it was my baby's first birthday, and we got back together. I don't know, he didn't want to be seen with me. I go to the club, and his My ex went and hugged him, and he humiliated me in front of her. When I asked him what he was doing, he told her to leave her alone, that she was crazy. Then the next day, he twisted things, saying that what I was saying wasn't true. He found a job and forgot about me and his children, even though he didn't have any. The only one who helped was me. His family disappeared, and then he lost his job, so he came back to me. I helped him with everything. His cell phone broke, I helped him fix it, and so on. He went to work, and with the money he earned, he bought barbecues for his family or gave them blowjobs for the holidays. He spent not a single year with them in the six years we were together. I decided to leave him after the 31st. In the weeks leading up to that, he was sending one thing after another again and didn't ask me if I had enough to feed the kids while he ate lavish barbecues with his family. I left him, and he was furious. He called me and sent messages, but he didn't bother me. Then he started an OnlyFans account where he asked me for videos. Without my face, of course, and I bought a phone with someone, and then I had a meeting with someone else, and that was it. I kept the messages, but I didn't delete them because I thought he wouldn't come back to my house. On Thursday, he showed up with noodles for my kids. He sent me to buy them because he was already chatting with me again, and I fell for it and let my son use my phone. I didn't have time to delete everything and close the account because I didn't want to, and I already had money. When I got back, he had checked my privacy settings. He told me he was disappointed in me. I got angry and said, "Well, show me your phone. How are you going to see mine?" He preferred to go and show it to me. Besides, he had been hiding his phone from me for a while and always made me turn away or covered it when he used it. From then on, he blocked me on Facebook, WhatsApp, and Instagram. He left me there, but he didn't ask about my kids again. Last night, I went to a party with my children, and I ran into him. He had the nerve to greet my kids as if nothing had happened and left my youngest crying because when his mother told him that The baby was left crying. He told her, "Leave him alone. You know I don't want to be near her. She hates me, and I'm the one suffering. I can't get out of what that narcissist did to me. This is me." Has anyone else experienced something similar, or were you able to get out? How?
