Idk what to do…

Me n my bf broke up we’ve been together for a year and I’ve been living with him and we argued and his parents now don’t want me there bc of the argument. He says to wait some months for him to get a place but I honestly don’t want to wait. I was so used to sleeping with him every night it just feels weird now I feel like what’s the point I’d rather be single. Idk why his parents are being like that if his brothers ex wife cheated on him and they still would send her money for her 4 kids that aren’t his. His sisters BF doesn’t work and they don’t say nothing and they’re living at one of his parents houses for 1k but they haven’t paid anything for months. His sisters baby daddy crashed her car into the lake and totaled it and they still treat him like a king when he goes over but they have a problem with a argument.. I’m 3 months pregnant and none of his family ever ask about the baby or how I’m feeling and when I show them sonograms they don’t even care which is fine oh well but my bf doesn’t understand he says my family doesn’t talk about you. I’m like ok whatever n he said I’m gonna regret leaving him ima end up missing him. All I said was I just needed a break.
