@rose is half right
Being married at 18 is too soon imo.
Plus it seems you want a barn/farm. I mean unless you date a well-established young farmer with parents with no debt, it will be most likely impossible for you to find unless you move in the slums of alaska/montana lmao
Also you need fuck tons of money to get that lifestyle. I'm 27 and even if i'm gonna bought our house this year or next year, and have already that farm lifestyle rn, it needs lot of work and sacrifices
You seem to be under 18 so you should just focus on school, get your grades, a proper paying job and then maybe later find your man.
