The odds of a marriage involving a 16 yo girl being successful long-term is quite slim. Often the partner is also young, or has been poorly chosen, or has a specific preference for very young women and will move on when she gets too old for him.
In this day and age, where two-job families are the norm, and a decent income is generally granted only to those who have college degrees or technical skills of some sort, getting married at 16 often means a life of poverty or struggle because marriage and higher education often don’t go well together.
My grandmother married a man who was 30 when she was 16, largely because she lived in a terribly strict Presbyterian household and was tired of childcare (she was the oldest of 11 at the time, and later the oldest of 12). Yes, her marriage lasted, but that was because the pair had only one child and shipped him off to boarding school, so she could continue in the role of Daddy’s Little Girl. It was also because in those days only “fast” or immoral people divorced, and also, since my grandmother had no skills that would make her employable, there was nowhere for her to go.
My cousin, several generations later, married at 16 and lived with her husband, an unemployed alcoholic house painter aged 46, in her bedroom at her mom’s house. By 19 she had realized that her life wasn’t going anywhere and that whatever little progress she made was being soaked up by bottles of booze, so she divorced.
Fortunately for her, her grandparents died about that time and left their considerable fortune to her parents. Her grandfather had owned a string of “shoppers,” those Penny-Saver-like lists of want ads, and a number of small town newspapers, and made lots of money with them. He made even more when he sold them. She was able to be supported by that money until she got her GED, got through college, got a good job, and eventually married a man her age.
I am skeptical that this marriage will turn out well, but I would always love to be pleasantly surprised. Several of my daughter’s classmates married as early as age 14. She is now a senior in high school, and we see the girls at various athletic events, pushing strollers and looking lonely and depressed.
