Idk if me and my bf should break up over moving in together

ik this whole thing might sound stupid and all but pls help

me 19 and my bf 18 have been dating for about a year now and i couldnt have found anyone better,we're both the same kind of date to marry type people all that corny shit but for some context he comes from a big joint family where everyone's close to each other,like some disney channel type beat idk and i come from the opposite just parents,one sibling and no one talks to each other, recently when we were talking about moving in together after marriage he told me he doesnt wanna move out of his house,he wants to stay with his parents and take care of them and all as he thinks it's his duty,mainly because his parents tend to fight and he'll be worried all the time when he's away,he didnt even go to the college he wanted to go to because of the same reason,and i on the other hand want to start a new life after getting married,i get his reasons obviously as i have always grown up with my parents fighting all the time,but i feel like i have a life of my own too and cant spend my whole life with my parents,and my parents too would expect me to literally move out by 21 but whatever. I've always been scared of ending up in a crowded joint family where you have no privacy and all,and he says he can never imagine not living in a joint family. I'm obviously not talking about isolating from families or anything but living alone i feel like is just a thing idk,,,,everyone does? like i never thought people wouldn't wanna move out no matter how close you are to your family. Whatever now ik it's a dumbass reason to breakup with soemone over but i dont wanna spend 10 years on this then after that we break up and i've have wasted half my life on smth that i knew was never gonna work out,i dont wanna breakup either idk what to do
