Need some opinions.... And need to vent

Im not sure what to make of this. I know it's abusive and whatnot but I need opinions and advice. Idk if I'm dealing with a narcissist or not. I just need some advice...

I was seeing this guy for almost a year and when we were together physically everything was great but he'd get mad if he couldn't see me. He has threatened to kill me, has said if I dksnt give it up to him he would get it from every female he could and still get it from me, he'd get really upset wirh me and say he fcked this girl but then turns around and says he didn't. I'm currently pregnant with his baby and he is doubting it's his and doesn't think I'm really pregnant. Even though I sent a video of a digital pregnancy test process with the "pregnant" result showing up. I even wrote my name on a piece of paper next to it to prove I am! I invited him to come to my first ultrasound in February just to prove it! He wanted to get me pregnant! Then after we found out I'm pregnant he gets upset with me telling me he wants me to have an abortion then takes it back saying he didn't mean it. I love him so much but idk what to do. I DONT love with him. He wanted me to move in with him ASAP after I found out about being pregnant and I said no. He got upset with me.

He's in Alaska right now and, I'm still on the east coast. He's there for work but he texted me saying he wanted "smash" (have sex with me) and I said no. He said that if I disnt he would get it from other females and still get it from me. He said he would take my baby from me and when I asked what his reasoning was his reply was "why not?"

Idk what to do or think. I'm just trying to get through the first trimester without puking my guts up. Help?? I know it's abusive but what would y'all do???

ETA: he lives about 7 minutes from my house. I also have three other children from a previous relationship. I know this is all over the place and I'm sorry. Do you think he is unstable?? Because I think he is but I'm confused by all my emotions right now.

ETA: would it be bad if I told him I had a miscarriage and just dropped him? Im only asking if it's bad if I told him I had a miscarriage? I really did love him and thought he loved me but y'all are really helping me realize further he isn't a good person. He's a military vet if that counts for something in dealing with mental illness.

Moving is impossible right now. I own this property and just paid $500 to fix my well. He does NOT have a key to my house, so there's that. I do have shot guns and a 9mm on hand. I have a couple friends who live in my guest house if I have trouble. One being a man there and his girlfriend. She is here 24/7.

I wanted a family with him. It's why I got pregnant. But it was also stupid too. I really thought he loved me though because when he wasn't going off on me he was sweet and loving. Like your typical abuser does and I fell for it. I know I'm stupid for letting him get me pregnant but I did want this too. I can do this on my own no problem. I just really wanted to be his wife but now I DONT. I really thought he was the one and my heart is broken so please excuse me for being naive and stupid. I'm just trying to wrap my head around this bs. 🥺 Thank you.
