Not knowing you, I can’t say if you are too young to marry. I’ve known plenty of 17 year olds and older people who act like they’re immature 17- year-olds who weren’t ready for marriage. But I’ve also known mature teens who probably would have been ready for marriage if they had chosen that path earlier in their lives.
That said, both of my grandmothers married before the age of 17. Both were elopements. My American grandmother and grandfather were 16 and 19 and was civilly married before my grandfather was shipped off to the Pacific as a marine in WWII. They got married, then immediately after she went back home with her grandmother (the only one who knew about it) and he went back to his place. 3 years later, when he came back wounded, they got it convalidated, had 6 children, and were married 50 years before he passed away. It was tough - he had to work 2-3 jobs to make ends meet, but they were happy.
My other grandparents were 14 and 21. That grandmother was extremely intelligent and mature. She grew up in a wealthy household in the Philippines, attended American schools (the American couple running the boarding school actually wanted to “adopt” her and take her back to the States) and was promoted to a senior in high school by the time she eloped with my grandfather - basically a “commoner”. She gave up all of her wealth and a betrothal to a wealthy Chinese businessman and life of luxury to marry my grandfather. She was/is very feisty and quick. They had 10 children and she was involved in local politics.
Both women, although young, were ready for marriage. I asked my caucasion grandmother what the difference was. She thought it was more of a different way of thinking. When she and my grandather were teens, yes, they had fun, but they were expected to grow up faster and to take on major responsibilities much sooner than most children today. They also understood sacrifice and doing without much more than my generation (in general) which is so used to having things now and not making too many sacrifices. Today we’re encouraged to prolong our youth, to complete our education and get a job before settling down. I can’t say which way was/is better, but I can definitely see the pros and cons of both ways of living.
Personally, I wouldn’t marry that young today, especially with how hard it is now to have a sustainable wage without a college degree or while getting a college degree. That could just be today’s societal influence speaking through me. But who am I to say that someone else isn’t ready?
