Filing for a restraining order

(Long post sorry)

I’m filing for a domestic violence restraining order on my ex boyfriend. We’ve been together for 3 years and have gotten into a few physical fights but I always ended up not leaving. This was the final time I’m letting him do this to me.

I’m currently 9 weeks pregnant and 2 days ago we got into a fight at his grandmas house. I was trying to leave and he grabbed me by my hair and pulled me so I turned around and smacked him and he preceded to punch me in the stomach. I was crying and said he wouldn’t see his kid after that. Then he wouldn’t let me leave the room and took my phone. I was screaming and trying to get out and he just kept grabbing me and pushing me away from the door saying “nobody is gonna help you keep screaming” he threatened to kill me if I kept his child away from him.

he finally let me outside but he still had my phone and told me I wasn’t leaving until his mother got there. Remind you I’m 23 years old and he’s 25. He finally gave me my phone back and I tried to get into my car to leave but he blocked me and got into my drivers seat. When his mom finally showed up she was just yelling and me while I’m crying and trying to get away from them.

I was finally able to leave and went straight to my parents house and called the police. The police filed a report but didn’t arrest him because he denied everything and I didn’t have a bruise from where he punched me.

I’m going to file a restraining order but I’m worried. I only have little evidence against him. I have one text where he threatened to shoot me. And I have one picture of a bruise on my arm from where he punched me a year ago. Other then that I don’t have much to go by.

He’s a known drug dealer and would even smoke in our apartment while knowing I’m pregnant. He’s also a big drinker. He has unregistered guns. I’m scared for my safety and the baby’s safety. He also got into a fight last weekend when he went drinking with his friends and currently has a broken jaw.

I’m scared they are not going to approve the restraining order. He does have videos of me screaming and yelling during these fights where he was trying to make me seem crazy and unstable but he was the one who started them. What suggestions would you guys recommend for me to be able to better prove his abuse.
