Please give me advice 😔

Why do I feel like I can’t get away? I’m obviously not happy in my relationship. He’s done the worst to me since day one. He KNOWS my mother is unstable and uses that against me to say “ask your mom if she has room in her house since you wanna leave so bad” or “goodluck at your moms”. It gets me every single time. That’s why I can’t leave. I have no where to go. I also can’t live with myself putting my son through this. Him going back and forth to different houses. Him not seeing his parents together. Not waking up to both of us. He tripped me this time. On the phone with his friend calling me names Bc I was upset. He was looking for something to throw at me and found my sock and launched it at my face. He stood at the door in front of me so I couldn’t leave. Holding his body there so I was trapped and force to listen to him. I. Don’t. Know. What. To. Do.

I start thinking that it’s better if I’m gone. I love my child and I want to be with my child. But it’s going to be SO hard. I don’t think I’ll find love again. Who’s gonna want me with a baby? I’m so insecure Bc of HIM. He makes me so insecure. Telling me “that guy wouldn’t even look at you twice, trust me” My heads about to explode. It’s filled with so many thoughts.
