College and marriage

So im not going to college and Im going to be a pastors wife/stay at home mom.. my boyfriend and I are planning on get married when I'm 19 and he's 20 (we're 18 and 19).

My family is constantly ridiculing me and telling me im stupid and messing my life up.. any opinions?

UPDATE: im going to have a part time job til we have kids, and after we have kids I am homeschooling them.
