This goes against what most have said, but at the time I was dating guys behind my parents backs, due to their rules of not dating until 16, I had full intention to eventually marry every single one of them... What happened was at least the 1st to my parents found out and forcibly broke us up, well the first guy turned out to be a loser anyway, the second guy (who at age 13 we had seriously spoken of marriage together) Is dead now, drowned when he had a fit in the river... the third, guy, Leigh 15, well lets not go there... he ended up moving away, as did Michael, and if it wasn't for Jacob I would never have ended up with the guy who was my best friend almost the whole way through...
Although this is not the norm My point is don't judge by age, there are 30 year olds out there who have never even considered marriage. also remember up until the last 100 years it was unusual for a 16 year old not to be married with at least 3 kids... think about that
