My boyfriend pointed a gun at me. Update

I’ve been in a relationship with my boyfriend for 4 years and we have a 3 year old together. I also recently found out that I was pregnant again. He has always been mentally abusive towards me the whole time we’ve been together. He’s made empty threats. But recently he bought a gun to ensure our “safety”. He now uses it to threaten me. He says things like if you try to leave I’ll shoot you. He threatens to shoot himself also. I have been trying to think of a plan to leave but I’m incredibly scared. I don’t have anymore friends and my family is so far away. He wanted to move far away so I wouldn’t be close to anyone I knew. I want to leave because I want me, my daughter, and our unborn baby to be safe. But it’s difficult and dangerous. Yesterday he pointed the gun at my head. He was so pissed off and our daughter came in the room and all he said was go to your room or I’ll blow your mothers brains out. I don’t know what to do. I feel so alone and have nowhere to go. I’m afraid of having to raise to kids on my own. I’m 19 and he’s 21.

Update:

Hello everyone. I have gotten away from my (ex) boyfriend safely with my daughter and I’m currently with my mom. Thank you to everyone who has given me advice and all the nice wishes. I’m so grateful that I have gotten away safe. I will be putting my daughter in counseling for a while and I will be going myself. Thank you all again ❤️.
