I think I need to break up with my boyfriend but I’m scared and pregnant and don’t know what to do

Hi I’m dash (18 F) and I need help figuring out what to do in my relationship with my boyfriend (18M) I guess this could also be considered general life advice help but Im not sure what to do, me and my boyfriend have been together about a year and recently I found out I was 16 weeks pregnant with his baby, when I came into this relationship we both agreed that we wouldn’t want kids he told me that he wouldn’t be helping me or talking to me ever again if I did keep the baby; he did say he’d help pay for an abortion which I would need I do not make enough money to pay for it on my own but he wants me to move in with him because he thinks my mom is mooching off of me because I help pay the rent, he says “that’s straight up just her taking all your money to live and your never going to be able to save if you stay in that house I promise you your mom is going to take all of your money and your going to be stuck there forever until you guys end up homeless without anything again just because your mom couldn’t get up and get a job of her own” I want to state that my mom is filing for social security and has been trying to get it for like 16 years, my boyfriend is saying she will never get it and we will never go anywhere, which I know is probably true she’s gotten so many denial letters but Id like to have some kind of optimism. He wants me to live with him, so I can get whatever Job I want there and I would never have to spend a penny on rent ever, but I don’t like his family I have only heard bad stories about them from him and now he’s just like “that’s the past they changed now” it’s been like 2 months I just don’t know, not to mention the city he lives in is a place I said id never move back to it was a promise I made to myself because that place feels like actual hell to me because I went through a lot there. He’s very annoyed I can’t look past it but I’m pretty sure I’m dealing with something untreated and I don’t want to be triggered back into the headspace I used to live in everyday I was there curled up on a couch by myself. He knows the whole story he just wants me to look past my bias. Also if I moved there I’d no longer have a ride anywhere until he saves for a car and there’s been some recently noticed issue with my kidneys I just don’t know if living there would be healthy I don’t really tend to care about my well being and I definitely don’t care if I go to doctors I feel like if I went to live there I would be spending all my time sleeping/ “sleeping” or working because my boyfriend doesn’t pay too much attention to my mental state just kinda gets annoyed when I’m depressed for too long because that means the room is staring to get messy and he just doesn’t know how to help when I’m depressed he just wants me to get over it but he gets depressed all the time and when he’s depressed it turns into him not even making eye contact with anything but screens all day because he just can’t handle anything else at the time I guess? Also when he was living here with me he hurt my dog Lou she’s just a little poodle mix but it was whenever she did anything he didn’t like but especially if she touched any of his things one time he kicked her right in her jaw because she nibbled on the ear of one of his stuffed animals he left on the floor. he lived here for a whole year and couldn’t get a job hardly even tried even and would have me buy him steak and stuff all the time and if I forgot it he’d get an attitude for a whole day but my mom is mooching off me ? And I brought up the fact that I didn’t want to live with him is because his family don’t have a good history with animals because like they had a dog that was so neglected if wasn’t even potty trained not to mention they think beating dogs is the only way they’ll truly learn but it just turned that dog into a scared dog, my lou is even scared of feet now 😭 she didn’t deserve that and I don’t think I should put her in that environment but he doesn’t seem to understand. I also said I wouldn’t want to move there because I would more than likely be disowned if I did because he said some very hateful things to my family and I feel if I move in with him I’d be cutting contact with my mom and I don’t have any friends at all for real where I live now or there for that matter if he hurt my lou again I’d just have to take a walk and go back and hold he doesn’t do it again or get rid of her and I love her very much I couldn’t just do that…. So my big question is should I stay or should I go now ?
