Boyfriend wants to buy a house

My boyfriend has been adamant about it for a while, while I’m looking at apartments he’s looking at houses. I’m 21 and he’s 25, been dating for a year now and I am scared of the financial obligation of being a homeowner right off the bat. I love him to death but he doesn’t understand the way it makes me feel. Living in a house with a man I’m not married to...just feels backwards. Theres steps to relationships right? Cuz he doesn’t think so.

What do y’all think?
