Inspired by one of the Knot "secret" posts about young marriages failing.
REALLY depends on what mindset you go into the marriage with. I was married at 19. We're celebrating 7 years of marriage and 9 years of "togetherness" this year. He's five years older.
I would NOT get married so young again, but I just wanted to prove that not all of those marriages fail.
And BTW - I still finished college and waited five years to get pregnant.
