Am I in the wrong?

So when my man and I first moved in together we talked about not having roommates. We agreed that it would just be him and I. I’m just at a point in my life where I’m 25 and want to start a life and a family of my own and don’t want to have some random people living in my home. We can afford our rent. So anyways we’ve talked about buying a home together and everything was fine. Lately he’s been saying that he’s going to buy a home and get roommates. I’m just so frustrated and he thinks I’m “acting out” for no reason. I really do not want to have roommates and I don’t get why him putting the house in only his name makes it okay now. I just want to have a great marriage with this man and have a family. He’s 30. I feel like at this point in our lives we need to focus on us and our future. Not have a party house with a bunch of different people living there (he’d want each room to be filled with a different roommate). Idk am I wrong for feeling this way? He says it’ll make it “faster and easier” to pay the house off. Why can’t we just be like Normal people and pay it off as we go. I’ve talked to him about this but it just turned into an argument. It always has to be his way and honestly I feel like just buying my own condo or something because I refuse to have a bunch of people living in my home.
