Infuriated 😡

About 10 months ago I was in a dv relationship . He drug me through dog shit , piss and dirt by my hair . Pushed me down the stairs , broke my back glass out of my vehicle with a 2x4 , JUMPED on my front windshield and said I ran over him & the list goes on . He then put a no contact order and a restraining order on me saying that I was the abuser afterwards . Cops sided with him … around that time I was also sleeping with my ex boyfriend due to the circumstances & ended up pregnant . Cut off ALL contact with my abuser and have said nothing to him since . Fast forward to a few days ago , my dv partner decided to text my “mom” … he told her he knew I was pregnant and there was a possibility that it was his . She then proceeded to send pictures of MY CHILD to him !! 🤬 turned around and messaged him asking him if he thought my son looked like his baby pictures 🤦🏻‍♀️ all he texted back was he wasn’t trying to start anything … I ended up messaging him a couple of hours after finding out that info & told him to stay away from me and my family & don’t worry about anything that pertains to me . He was “upset” by my reply of course but I blocked him so there would be nothing further said . Went to the store a couple of hours after that ordeal and he POPS up at the store I was at and waited on me to get my stuff and pulled off . I just want me & my child to remain safe and away from him but some people tell me that I’m wrong for keeping him away if he is the dad , what do you guys think ?
