I need serious advice

Hi so my situation is very complicated, I’m a single mom, with an 8 month old. My ex partner, honestly does anything and everything to make me miserable. I left him during my pregnancy because he assaulted me and wanted me to lose our daughter. Got the police involved, went through court, etc. the state decides to drop his case because he is a “first time offender” and everyone deserves a second chance which I believe is crazy to me. I feel personally the system failed me and my daughter, the restraining order was lifted after the case was dropped.

Didn’t allow him at the birth, my daughter doesn’t have his last time, and I fought for months, but he took me to court to get his name on the birth certificate.

His family tries to paint me as the worst human being for “ruining” their sons record. My ex and I don’t get along at all. But I can say I’m the mature one in everything, never have I disrespected him. Lately he’s been telling me that he wants to have my daughter sleep over Monday-Tuesday because those are his only days off. But I told him I don’t and will not ever feel safe with leaving her alone with him.

He got into a huge argument with me saying that all I’ve done in his life is made him miserable and ruined his life. That I was never enough for him, “pretty enough” and that I’m not normal because I have health issues. He also said that he hopes my daughter isn’t like me because I’m just a sad individual ( he knows I’m going to therapy for my depression and anxiety that I got from him and from the day he assaulted me)

I allow him to visit his daughter supervised. But even then sometimes after he leaves he goes and parties and drinks. I don’t want that around my daughter. Then proceeds to call me all these horrible things on social media. That I’m a “hoe” that I’m a bitch and that he’s annoyed he gave me a child.

Am I wrong for feeling the way I feel? He thinks I’m being spiteful, but I’m just here protecting my daughter. I always tell him, being a good father isn’t something you get automatically biologically.
