I need some advice mommies!

Okay so this is my 2nd baby & my boyfriends first baby & boooy have we been on a roller coaster! I am currently 26 weeks & 2 days. I am 23 years old and he is 24. So the current situation is that my boyfriends parents were voluntarily deported and my boyfriend is now having to raise his 12 & 14 year old sibling. My boyfriend has another brother who is 21 but is not responsible and seems to not care about anything but himself and his gf. So basically my boyfriend and I have been taking care of the kids since January but I stopped working in March. His 14 year old brother has been disrespectful so I don’t really talk to him unless 𝐍𝐞𝐞𝐝𝐞𝐝 because the parents apparently think I provoke him to act the way he does when my boyfriend has even told his parents that I really don’t talk to him at all. All because when we were on lockdown he wouldn’t listen and sneak out the house while my boyfriend was at work. So at this point I was getting fed up because 1 I have a 3 year old and 2 I’m pregnant and I have a very weak immune system so I was super protective! So i would tell my bf about the little brother sneaking out and finally he told his parents what the 14yr old was doing but the parents had the nerve to say i provoke him? How is that provoking Someone? Last I need is for him to get covid and then get blamed for it cause it’s under my watch (so this please tell me where I’m wrong?). Okay so anyway my boyfriend has not been involved in my pregnancy whatsoever because he gets home at 5pm and wants to play video games or watch videos until about 1:30am every single day. He doesn’t ask how I’m doing or how the baby is doing. I have really bad Pelvic Floor pain and it’s no fun to the point where now at 26 weeks it’s getting hard to get out of bed but he doesn’t seem to care. His siblings are doing online school and he has no j Teresa in that whatsoever because he’s so stuck on his game all the time I clueing the weekends. Weekends are the worst because he wants to sleep in until about 2pm wake up eat and play video games like there’s nothing else to do. My dad is currently looking to buy a house and I want to love in with him because I’m not happy in his home with his sibling as they talk about me behind my back and my boyfriend tells me and they make me feel uncomfortable. Like I can’t even have my brothers over or even invite my parents because those kids don’t know how to act. Am I wrong for wanting to leave and move out? Do I break things off with him or leave and see how things go? I get he’s “stressed over the kids” and he says he has a lot of “sh!t going on” but I’m pregnant. I was 4 months pregnant and he had the nerve to say he had to much shit going on to be worried about this(as in our relationship/pregnancy). Help! What do I do? And I’ve talked to him sooooo many times, I’ve given him tooo many chances. At this point I’m over it.
