Should i 23F break up with my 28M boyfriend?

i’ve been dating this guy for just a month. i really like him and think he’s great, but there are just some big differences, im too nervous to voice my thoughts to him especially since we aren’t serious.. so i thought. i spend a few nights a week at his house, today he told me that i should just move in. i thought he was joking and he.. wasn’t. he wants me to move in asap so we can start having children. i was shocked and suddenly ready to go. he’s continuously told me that he wants 10-12 kids, that’s a lot of children. we have talked about that, he doesn’t budge, he wants a big family. there are many things he doesn’t budge on; he already has the names of all his kids picked out, he wants to raise his daughters to be only house wives, he refuses to tell me things about himself (such as why he was arrested prior, details of his previous girlfriend suing him?) etc. it’s a lot. i’ve always thought of myself having 3-5 kids (thinking that’s a lot) and i would like to raise both genders equally. if my daughters wanted to be business women that’s fine with me.

in the month we’ve known each other he’s taken me on 3 trips, and another one coming up on valentine’s day, he’s always super sweet and affectionate. when i get upset at him he does try hard to put me in a better mood, i can tell he genuinely is a sweet guy. i just really need some other thoughts on the situation, are these things going to cause issues down the line?
