Psycho ex/babydaddy(help)

My ex is saying in order for him to move on he needs me to tell him I’m having sex with someone. Every time I take my daughter to see him he argues with me and ruins my mood. He will sit in my car for hours and proceed to say I need to tell him or else he can’t get over me. I am seeing someone but I feel that is none of his business. He says the moment he finds out he will harm/kill this person. I left him because he’s controlling and abusive. Emotionally, mentally, physically, financially. You name it. He paid the neighbors to tell him when I was home or not. He threatens to stalk me since I will not tell him anything. Last night I went to pick my daughter up and he starts getting physical with me and not letting me leave. He was reaching under my dress trying to feel my vagina and saying “them let me see if you’re wearing panties or not”. We have not been together over a year and he still acts this way. The only way I was able to leave was the security guard coming over after me screaming and honking my horn and threatening to call the cops. He was snatching my phone as I’m crying and screaming for him to leave me alone. He keeps calling and texting me saying it’s my fault. When I have done nothing to him but try to move on and live my life. I am tired of being abused. I am afraid of having no help. He only watches her 2 days. But now I have no one to watch her. I have lost my job due to this virus. I don’t know what I am going to do. And he is not making it easier. What can I do for assistance or anything? I want to get a restraining order also but not sure if I should. I have no babysitter anymore because he watches her 2 days and my sister watches her any other days. I just want a little guidance. I have no one and I am tired of being mistreated for help. Any ideas would help please and thank you. He disgusts me so much and I never want to speak to him again. He says if I have sex with him he will stop acting crazy.
