Marrying young..

Hi! Just wanted to see what yalls opinions were on marrying young. I'm 16, and have been in a relationship with my boyfriend for well over a year now & he's about to turn 18. We are sexually active as well. I don't know what the future holds for us, but I hope there's a chance of us getting married when I'm out of high school & 18 y/o of course.  I know there has been harsh remarks about how being married when you're only 18 or 19 is too young and a little crazy but I'm honestly in love with the fact you get to spend your life with someone & grow with them, even at a younger age. Lemme know what yall think!!
