Should I tell? UPDATE!!

So I'm gonna start from the beginning.

Around march my childs father started dating. Everything was going great and then all of a sudden we started going down hill really fast. We were always broke living in and out of my car and a tent. He was very manipulative and very disrespectful. He would call me stupid and treat me very bad. Well I stayed with him up until a few weeks ago. I broke up with him because he threatened to shoot my family if they ever got behind my car again while he was driving. We were on our way to the rest area where we had been staying when I finally called my mom sobbing because I was so scared. We had stopped at the store to get some drinks and food. Finally my mom and dad pull up and my ex takes off in his car and my dad follows meanwhile my mom is sitting with me at the store waiting for the cops to show up. Well they show up and they told me to get an order of protection. So the next day that's what we go and do. We have court on the 25th of this month. Well on the 12th I found out that I'm pregnant and now I dont know if I should even tell him or his family. His family was nothing but nice to me and treated me with respect. He is 28 has no job no car and doesnt wanna better himself he has been in and out of jail for awhile now and might go back pretty soon. He already has 2 kids he doesnt see because his ex wife wont allow it and honestly I dont blame her. My question is should I even tell him? Should i feel guilty if I dont? I'm so confused and at a loss idk what to do with myself please help😭😭

I want to thank everyone who commented on this post and gave me great advice. I will be leaving him in the past forever. He will never know about my little blessing and I start school in a month to become an RN. I know it wont be easy and it will some long nights and days but it will be so worth it!! I will be talking to a lawyer about making sure he will never be able to take my baby from me. I'm ready for April 22nd to be here!! Whoop whoop!!🤰👶
